What is the equation of 3(5x+2)=8x+20

Ivan

Answer:

x=2

Step-by-step explanation:

3(5x+2)=8x+20

Distribute the 3

15x +6 = 8x+20

Subtract 8x from each side

15x-8x +6 = 8x-8x+20

7x+6 = 20

Subtract 6 from each side

7x+6-6=20-6

7x=14

Divide each side by 7

7x/7 = 14/7

x=2

Sally painted a picture that has an area of 480 square inches. The length of the painting is 1 1/5 its width. Which of the follo

prohojiy [21]

A = 480
W = x
L = 11/5*x
therefore 480 = 11/5*x*x
480 = 11/5x^2
480*5 = 11x^2
2400/11 = x^2
$+ or-\sqrt{2400/11} = x$
However we can't have a negative width so width is $\sqrt{2400/11}$
Sub this into the length equation to find length $\frac{11}{5} * \sqrt{2400/11}$
