Answer:
9
Step-by-step explanation:
The length of the paper , x, can be obtained using Pythagoras :
Width = 12 ; length = 15
x² = 15² - 12²
x² = 225 - 144
x² = 81
x = sqrt(81)
x = 9
Hence, length of the paper = 9 inches
Answer:
The graphs intersect at (6,-1)
A) x = -3 x = -1
b) x = 9 x = -5
c) x = -4 x = -2
3/5 of 400=x people used it
so we x=400x3/5
x=240
so 240 people used it again.
