2b^2 - 3b + 4a^2....a = -6, b = 8

2(8^2) - 3(8) + 4(-6^2) =
2(64) - 24 + 4(36) =
128 - 24 + 144 =
248 <==

we conclude that the dimensions and area of the scaled figure are:

  • l₂ =  48 in
  • w₂= 32in
  • A₂ =  1,536 in^2

How to find the dimensions of the large rectangle?

First, we know that the large rectangle is the smaller rectangle rescaled, with a scale factor k = 4.

This means that each dimension of the smaller rectangle must be multiplied by 4 to get the correspondent dimension on the larger rectangle.

The dimensions of the smaller rectangle are:

l₁ = 12in

w₁ = 8in

Then the correspondent dimensions of the large rectangle are:

l₂ = 4*12in = 48 in

w₂= 4*8in = 32in

Now, the area of the large rectangle is given by the product between the two dimensions, we will get:

A₂ = 48in*32in = 1,536 in^2

Then, we conclude that the dimensions and area of the scaled figure are:

  • l₂ =  48 in
  • w₂= 32in
  • A₂ =  1,536 in^2

Given that (2*(x -3) ) / 8*( 2 y - 3) = 16*( x - y )​
lyudmila [28]

Answer:

2 ^ (x - 3) ÷ 2 ^ 3(2y - 3)=2 ^ 4(x - y)

The two are common so we give it out then

x - 3 ÷ 6y - 9 =4x - 4y

x - 3 -4x - 4y = 6y -9

-3x -2y = -6

6=3x+2y
