The area of a square is 9/16 in2. What is the perimeter of the square
Alekssandra [29.7K]

Answer:

3 in²

Step-by-step explanation:

The fraction 9/16 is equal to the equation 9 ÷ 16.

9 ÷ 16 = 0.5652

Lets find the square root of 0.5652

\sqrt{0.5652} = 0.75

So the length of one side is 0.75 in²

Now we'll multiply this by 4, for the length of the 4 equal sides.

0.75 x 4 = 3.

This means the perimeter is 3 in².

Solve for substitution 8x+2y=13 and 4x+y=11
damaskus [11]
Solving for X:
1) y=-8x+6.5   y=-4x+11
2) -8x+6.5=-4x+11
3) -8x=-4x+11-6.5        (Subtract 6.5 from both sides)
4) -8x+4x=11-6.5         (Add 4x to both sides)
5)-4x=4.5
5)x=-1.125

Solving for Y:
y=-8(-1.125)+6.5
y=9+6.5
y=15.5

y=-4(-1.125)+11
y=4.5+11
y=15.5

x=-1.125
y=15.5
or
(-1.125,15.5)
