The length is 9.
The formula to find the perimeter of a rectangle is
2L + 2W = P.
2L + 2(4) = 26.
2L + 8 = 26.
2L + 8 (-8) = 26 (-8).
2L = 18.
2L/2 = 18/2.
L = 9.
Answer : 96
x – y = 16
--------> equation 1

x is the higher grade and y is the lower grade
We solve the first equation for y
x - y = 16
-y = 16 -x ( divide each term by -1)
y = -16 + x
Now substitute y in second equation



Take common denominator to combine fractions


Add 8 on both sides

Multiply both sides by 
x = 96
We know x is the higher grade
96 is the higher grade of Jose’s two tests.
