1/4(x+3)=4(x+3)

what is the solution? will give brainliest. please show work or explain!

x=3

Step-by-step explanation:

You multiplie 1/4 to x+3 and 4 to x+3

1/4x + 3/4= 4x+12

You subtract 12 on both sides

1/4x -11 and 1/4= 4x

You then subtract 1/4 x on both sides

-11 and 1/4= 3 and 3/4x

Then divide 3 and 3/4 from both sides

-4

step-by-step explanation:

do 6-10=

if u need it to be negative.

a≈380.13mi² would be your answer if the radius was 11 miles
