Answer:
y=10
Step-by-step explanation:
8(7-y) =-24
WE APPLY DISTRIBUTIVE PROPERTY:
8*7 -8*y =-24
56 -8y=-24
56+24=8y
80 = 8y
y=80/8
y=10
Answer:
Step-by-step explanation:
1. ok so you need to use Pythagoras which is a^2 + b^2 = c^2
substituting 16 and 12 into 'a' and 'b' you get 16^2 + 12^2 = c^2
256 + 144 = c^2
400 = c^2 (square root each side to get ride of the square)
c = 20cm
2. doing the same thing you get c = 22.36 in
3. again doing it you get c = 15Ft
Hope this helps!
To find the side lengths, you have to factor 4x^2 + 28x + 49. This equation factored is (2x+7)(2x+7), so each side length is (2x+7) feet.
It’s 4/15
Answer = 3 3/4
I hope that helps :)
