The area of a rectangular invitation card is 3/10 square foot. given that the length of the card is 4/5 foot, find its perimeter.

First, you have to calculate for it's width.

3/10 = 4/5 * w

w = 3/10 * 5/4 = 3/8

Perimeter = 2(l+w) = 2(4/5 + 3/8)

P = 94/40 = 47/10 ft = 4.7 ft

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
