Answer:
9
Step-by-step explanation:
you want the trinomial (x*x - 6x + __ ) to be written as a binomial squared.
So we would need to realize that the constant would be equal to (-6/2)^2 =(-3)^2 = 9
We have completed the square.
f(x) = 4*( x - 3)^2 + 20 is now in Vertex Form
$29.50 + $10.50 = $40
Answer: They gave her $40!
Answer:
140=10x
14=x
Step-by-step explanation:
I believe that the answer is C, I don't know if it is addition or multiplication, but if is is addition, it would be 146, C
Answer:
5. P = 23 m
A = 15 
6. P = 24.4 in
A = 15.3 
Step-by-step explanation:
Area formula of a triangle is A = 1/2 bh
Area formula of a parallelogram is A = bh
5. The height of a triangle is perpendicular to the base.
A = 1/2 * 10 * 3
A = 15 
6. The height of the parallelogram is also perpendicular to the base.
A = 9 * 1.7
A = 15.3 
Perimeter means you add all the side lengths.
5. The side lengths are 5m, 8m, and 10m. Adding those together, you get 23m.
6. A parallelogram has congruent opposite sides. That means your side lengths are 9 in, 3.2 in, 9 in and 3.2 in. Adding those together, you get 24.4 in.
