Find the sum of (x + 5) and (2x + 3) *

A) 9x + 1
B) 5x + 2
C) 8x + 3
D) 3x + 8

D

Step-by-step explanation:

We know that we are adding the two expressions because the question says "sum" which means that we need to add. Let's combine like terms. We know that x + 2x = 3x and 5 + 3 = 8 so the answer is 3x + 8.

D. 3x+8

Step-by-step explanation:

We want to find the sum of (x+5) and (2x+3). Sum means addition, so we must add the 2 expressions.

(x+5)+(2x+3)

Now, we must simplify by combining like terms.

First, combine the terms with variables.

(x+2x) + (5+3)

3x + (5+3)

Next, add the constants, or terms without variables.

3x+ 8

The sum of (x+5) and (2x+3) is 3x+8. This makes choice D the correct answer.

i dont know

step-by-step explanation:

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

the factor is 2

step-by-step explanation:

let f(x)=8(3^(x−2)+2)

to stretch a graph by 3, it would be 3f(x)

g(x) =3f(x)

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

x     −2     0     2     4     6

f(x) 1/64 1/16   1/4     1     4

1/64 * z * z = 1/16

i multiplies by z twice because it its 2 steps from -2 to 0

1/64 z^2 = 1/16

multiply by 64 to clear the fraction on the left side

1/4 * 64 z^2 =1/16 *64

z^2 = 4

take the square root of each side

sqrt(z^2) = ±sqrt(4)

z = ±2  

we are multiplying by 2 each time.
