Answer:
10
Step-by-step explanation:
using HYPOTHENUS theorem
8^2 + 6^2 = x^2
64 + 36= 100
√100=10
A=LW, we are told that the dimensions are 42 and 48 so:
A=42*48
A=2016in^2
The (3, 1/5) would be a solution while the (-1,1) wouldn’t because when you write this equation in the slope intercept form which is y = 3/5x - 8/5
1/5 = 3/5 (3) - 8/5
would end up with 1/5 = 1/5 which is write
While,
1 = 3/5 (-1) - 8/5
Would end up with
1 = 11/5 which is wrong
Answer:
a=-0.5
Step-by-step explanation:
Distributive property for left side, difference of squares for right side.
8a-9a^2=-40+36-9a^2
-9a^2 cancels out
8a=-4
a=-0.5
