Answer:
Step-by-step explanation:
We have been given that are two racks with 40 towels per rack. On Tuesday there were 30, on Wednesday 50 and on Thursday 25. We are asked to find the fraction on average that is in use for the three days.
First of all, we will find total number of towel by multiplying 40 by 2.
Now we will find average number of towels used on three days.
Now we need to calculate 35 is what part of 80 to find the fractional use of towels per day as:
Therefore, on average is in use for the three days.

Answer:
(d) (-2, 6)
Step-by-step explanation:
We can rewrite the function using vertex form.
f(x) = (x^2 +4x) +10
f(x) = (x^2 +4x +4) +10 -4 . . . . . . . add and subtract (4/2)^2
f(x) = (x +2)^2 +6
Compare to vertex form:
f(x) = (x -h)^2 +k
we see that (h, k) = (-2, 6) . . . . the vertex
_____
<em>Additional comment</em>
The value added and subtracted is the square of half the x-coefficient. Inside parentheses, that value "completes the square". Outside parentheses, that value ensures the overall function remains unchanged.
Wouldn't it be divide or D because square roots is dividing
Answer:
Step-by-step explanation:
Compare the powers
x² + 4x + 4 = 9x + 18
x² + 4x + 4 - 9x -18 = 0
x² -5x -14 = 0
x² -7x + 2x - 2 *7 = 0
x(x-7) + 2(x - 7) = 0
(x-7)(x+2) = 0
x - 7 = 0 or x + 2 = 0
x = 7 or x = -2
