Answer: 252
Step-by-step explanation: 21x-12=252
A^2+b^2=c^2
8^2+b^2=10^2
64+b^2=100
minus 64 both sides
b^2=36
sqrt both sides
b=6
the leg is 6ft
Answer:
zeroes: x = -9 and x = -7
Step-by-step explanation:
f(x)=(x+8)^2−1
A "zero" refers to when the y-value on the graph is zero.
0 = (x+8)^2 - 1
1 = (x+8)^2
+ or - 1 = x+8
so break them apart into two equations
x+8 = 1 OR x+8 = -1
x = -7 OR x = -9
You can plug both back in to check that the equation works!
