Answer:
84 Square Inches.
Area = Side length x Side length
All you do is subtract 3.2 from the number 4 and you get the number -0.8
Answer:
38
Step-by-step explanation:
A graph shows PQ = QR when x=-1 and PQ = QR = 19.
Then ...
PR = PQ + PR
= 19 + 19
PR = 38
_____
If you want to solve this algebraically, you can set PQ = QR:
6x +25 = 16 -3x
9x = -9 . . . . . add 3x -25
x = -1
PQ = 6(-1) +25 = 19 . . . . this is half the length of PR
PR = 2×PQ = 2×19
PR = 38
