Answer:
Step-by-step explanation:
This is a parabola with a vertex at h = 4 and k = 5; the graph goes through the coordinate x = 6 and y = 6. We will use those 4 values to fill in the equation:
and this will allow us to solve for the value of a:
and
and
6 = 4a + 5 and
1 = 4a so
and the equation is

Answer:

Step-by-step explanation:

Cancel out 6 in both numerator and denominator.
Rationalize the denominator of
by multiplying the numerator and denominator by
.

The square of
is 2
Factor 14=2 × 7. Rewrite the square root of the product
as the product of square roots
.

Multiply
and
to get 2.

Cancel out 2 and 2.

Answer:
B (12)
Step-by-step explanation:
The expression can be written as the following:
(2n)(n-1)
Let n=3
(2*3)(3-1)=(6)(2)=12
So the answer is B (12).
Answer:
5. (x-8)(x+2)
10. (x-5)(x-5) OR (x-5)^2
36 + h = 75...subtract 36 from both sides
h = 75 - 36
h = 39
-176 = h + (-219)
-176 = h - 219....add 219 to both sides
219 - 176 = h
43 = h
