Answer:
Step-by-step explanation:
If it is, the first and last terms are perfect squares, and the middle term is twice the product of the roots of those squares.
16x^ = (4x)^2 . . . . a perfect square
49 = 7^2 . . . . . . . a perfect square
-2(4x)(7) = -56x . . . . . matches the middle term, so the factoring is ...
16x^2 -56x +49 = (4x -7)^2
_____
The sign in the binomial factors is the same as the sign of the middle term of the trinomial.
Answer:
12
Step-by-step explanation:
you divide 36 by 3 and get z = 13
The volume of a cylinder is given by
Let 
and 
The new volume becomes
So, the new volume is 8 times the original volume. In fact, volume scales linearly with the height and quadratically with the radius.
Answer:
m∠C = 118°
Step-by-step explanation:
180 - 56 = 124°
124 ÷ 2 = 62°
180 - 62 = 118°
m∠C = 118°
