Answer:

Step-by-step explanation:

use substitution and solve this 8x+4(-2x+3)=12

with the 4 distributed its

8x-8x+12=12

then you can cancel out the 8x and -8x and switch the 12 over into a -12 canceling out the 12s making it x=0

Find the area to this problem

Papessa [141]

Answer:

254.34 in²

Step-by-step explanation:

Given:

Diameter of the circle = 18 in

To find:

Area of the circle

Solution:

Let the area be a.

First, we find the radius of the circle by dividing the diameter by 2.

This comes out to be 9 in.

Now, we apply the formula

$a = \pi \times {r}^{2}$

Solving, we get

a = 3.14 × (9)²

a = 3.14 × 81

a = 254.34 in²

Hope this helps! :D
