- 6g + 2a + 3 + b + 4a ( 6th term )
- 2 ( 3a x 4 ) + 4x = 3^2 ( 5th term )
b. Factorise completely :
3x² + 9
c. Solve the following inequality :
2x + 3 > 17
-Please, please help me asap! ♡´･ᴗ･`♡
Answer:
e=9
sorry thats all i know:(
Step-by-step explanation:
Answer: b.) 3x^2+9 factorized= 3(x^2 +3)
c) solving inequality: subtract 3 on both sides, take that answer and divide by 2 on both sides. answer is x>7

Step-by-step explanation:
Step 1: Define Equation
3(4x - 5) - 4x + 1 = -6
Step 2: Solve for x
Distribute 3: 12x - 15 - 4x + 1 = -6Combine like terms: 8x - 14 = -6Isolate x term: 8x = 8Isolate x: x = 1Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 3(4(1) - 5) - 4(1) + 1 = -6Multiply: 3(4 - 5) - 4 + 1 = -6Subtract: 3(-1) - 4 + 1 = -6Multiply: -3 - 4 + 1 = -6Subtract: -7 + 1 = -6Add: -6 = -6Here we see that -6 does indeed equal -6.
∴ x = 1 is the solution to the equation.

15/40 = x/13,095
solve for x then round to the nearest amount of whole hours.
PLEASE ANSWER ASAP!
Answer:
Step-by-step explanation:
You can cross multiply (15 x 13095) = 40x
196425 = 40x
divide by 40
x = 4,910.625
x = 4,911
x = - 5
x ^ 2 + y ^ 2 = 25
show work also
Step-by-step explanation:
Since x is equal to -5, you would need to substitute that value for x in the equation x^2 + y^2 = 25. So....
-5^2 + y^2 = 25
(-5)*(-5) + y^2 = 25
25 + y^2 = 25
y^2 +25 - 25 = 25 - 25
y^2 = 0
y = 0
(x, y) = (-5, 0)
To check the answer....
x^2 + y^2 = 25
-5^2 + 0^2 = 25
25 + 0 = 25
25 = 25
The answer should be correct, if not i am extremely sorry

(5,6) and (−5,12) what is the rate of change??
Answer:
- 0.6
Step-by-step explanation:
Start point: (5,6)
End point: (-5,12)
rate of change = (12-6) / (-5-5) = 6/-10 = - 3/5 = - 0.6
Answer:
The rate of change is -0.6
Step-by-step explanation:
Given
[tex](x_1,y_1) = (5,6)[/tex]
[tex](x_2,y_2) = (-5,12)[/tex]
Required
Determine the rate of change
The rate of change means the slope (m) and it is calculated as thus:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{12-6}{-5-5}[/tex]
[tex]m = \frac{6}{-10}[/tex]
[tex]m = -\frac{6}{10}[/tex]
Simplify the fraction
[tex]m = -\frac{3}{5}[/tex]
[tex]m=-0.6[/tex]
The rate of change is -0.6

22+15x=34-17x
Step-by-step explanation:
22+15x=34-17x
So now, the 34 will join the 22 and the 15x will join the -17x
22-34=-17x-15x
-12=-2x
So now, we divide both sides by -2x
and the negative will cancel negative so

Parallelograms s and t are each labeled with a base and a corresponding height
Answer:
Parallelogram S:
b = 7 and h = 6
Parallelogram T:
b = 3 and h = 6
Step-by-step explanation:
The given information is incomplete and is not enough to answer the question. (See attachment for complete question)
Required
Determine the values of b and h for both parallelogram
The question will be answered by observing the features of each parallelogram and recording the required values
For parallelogram S.
The vertical arrow at the left-hand side represents b and the arrow highlights 7 grid boxes.
Hence:
[tex]b = 7[/tex]
The horizontal dotted lines represents h and this line highlights 6 grid boxes.
Hence:
[tex]h = 6[/tex]
For parallelogram T.
The horizontal arrow represents b and the arrow highlights 3 grid boxes.
Hence:
[tex]b = 3[/tex]
The vertical dotted lines represents h and this line highlights 6 grid boxes.
Hence:
[tex]h = 6[/tex]

Why is the percent increase from 45 to 75 not equal to the percent decrease from 75 to 45? Select three options.
UThe amount of change drent for the percent increase and the percent decrease
UThe ratio of the percent increase is not the same as the percent decrease.
OThe ratio for the percent increase has a smaller denominator than the percent decrease.
U The ratio for the percent increase has a different numerator than the percent decrease.
O The original amount for the percent increase is different from the original amount for the percent decrease.
Answer:
work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. % increase = Increase ÷ Original Number × 100. If your answer is a negative number, then this is a percentage decrease.
Step-by-step explanation:
Which of the following situations are equal to 4? Select all that apply.

B) 80% of 5
C) 60% of 5
D) 20% of 20
E) 25% of 16
Answer:
A, B, D, and E
Step-by-step explanation:
honestly, if you just look it up 50% of 8 it will calculate it for you. You can do this with each question until you find the answer. When you look up each answer A, B, D, and E all were 4 soo hope this helps :)

Find the nth term of this quadratic sequence 3 8 15 24
Answer:
35
Step-by-step explanation:
A quadratic sequence is a form. of mathematical progression of numbers in which the subsequent differences between each consecutive term differ by the exact amount. This is known as the common second difference.
Hence in this case,
we have
S= 3+8+15+24+…..+Tn - 1.
S=. 3+8+15+……………..Tn-1 + Tn
Deducting 2nd series from the first
We have 0=3+5+7+…….Tn
Hence, we have Tn= n (n+2)
= 24 (9+2)
= 24 + 11
= 35

Carlos visita a sus abuelos cada 12 dias y su hermana sofia,cada8 dias.La ultima vez que conincidieron en la visita fue el dia 3 de enero ¿cuando volveran a coincidir? ¿cuantas veces habran visitado a sus abuelos cada uno entre los dos periodos que han coincidido?
Responder:
27 de enero
Horas de visita al abuelo antes de que coincida el horario = 1 vez
Horas de visita a Sofía antes de que coincida el horario = 2 veces
Explicación paso a paso:
Para obtener la hora en la que coincidirá su visita, obtenemos la L. C. M de 12 y 8
Abuelos (cada 12 días)
12:12, 24, 36, 48, 60, ...
Sofia (cada 8 días)
8: 8, 16, 24, 32, 40, ....
El mínimo común múltiplo de 12 y 8 es 24.
De ahí que su encuentro vuelva a coincidir a los 24 días.
3 de enero + 24 días = 27 de enero
Horas de visita al abuelo antes de que coincida el horario = 1 vez
Horas de visita a Sofía antes de que coincida el horario = 2 veces
