A square picture with a side length of 4 inches needs to be enlarged. The final area needs to be 81 square
inches.
Which equation can be used to solve for x, the
increase in side length of the square in inches?

x²+8x-65=0

Step-by-step explanation:

The equation to be used is

A=side²

The increased side = X

(4+x)² =81

x² +4x+4x=16=81

x²+8x+16-81=0

x²+8x-65=0

Option C

Step-by-step explanation:

edge 2021

have a nice day :)

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.

are ya tryin to ask something or is this a statement
