A^2 + b^2 = c^2
8^2 + b^2 = 12^2
64 + b^2 = 144
b^2 = 144 - 64
b^2 = 80
b = sqrt 80
b = 8.9 ft <===
Answer:
Rearranging Formula. This unit covers rearranging formulae. The manipulation of algebraic expressions is an important ... Changing the subject of a formula .
Step-by-step explanation:
The surface 5 cm, and the length is 10 cm
90+30x+30y. This is because the first day, 90 labels were printed, then you will use 30 times x to find how many minutes. This is the same for 30 times y. Youre trying to figure out how many minutes each machine printed for.
the answer would be A.
7x × X gives you 7x^2
7x × 2 gives you 14 X
so the answer is the square root of 7x^2 + 14 X
