Answer: this is Judy Heckman you answered a question about a parabola graph and someone went off of it before I could study it. Help thanks
Step-by-step explanation:
Answer:
d. p = 2*20 + 2*10
Step-by-step explanation:
You know to find the perimeter, just add side + side + side + side.
And two pairs of sides on a rectangle are congruent, so the missing side lengths based on the width and length, will be 20 & 10.
So add 20 + 20 + 10 + 10.
To simplify this, say 2*20 and 2*10. And then add them.
So it is D
Answer:
C
Step-by-step explanation:
9x² - 4
can be factored as a difference of squares , that is
(U + V)(U - V)
9x² - 4 = (3x)² - (2y³)²
with U = 2x and V = 2y³
Answer:
A: 270 ,':)
Step-by-step explanation:
The answer is A, 1. In the statement x^2 >x, if we try 4, 5 and 8 for x, we get 16, 25 and 64 for x^2. The statement is true. But if we try x = 1, when we square it we still have 1. Therefore for x=1, x^2>x is false.
