<h2>
Explanation:</h2>
First of all, we need to know that:
From the problem, we know that:
Converting gallon to quarts:
<u>For Angela:</u>
<u>For Ryou:</u>
<h3>
Part 1. How many walls will be blue and how many walls will be white?</h3>
Number of blue walls:
So we can paint 3 walls.
Number of white walls:
So we can paint just one wall.
<h3>
Part 2. How much paint will be left over?</h3><h3>
</h3>
For blue paint:
We can solve this by a rule of three as follows:
For white paint:
We can solve this by a rule of three as follows:
perimeter = 2L +2W
from the problem we know P = 74 and W=L-9
so 74 = 2L +2W
74 = 2L+2(L-9)
74 = 2L + 2L -18
74 = 4L-18'
92 = 4L
L=23
W=14
Answer: f(a-2) = 2a² - 14a + 28
Step-by-step explanation:
f(x) = 2x² - 6x + 8
you can take a-2 and substitute it for each x, which would look like this:
f(a-2) = 2(a-2)² - 6(a-2) + 8
then distribute those in ( )
f(a-2) = 2a² - 8a + 8 - 6a + 12 + 8
combine like terms
f(a-2) = 2a² - 14a + 28
Answer:
16w^2 - 24w + 9
Step-by-step explanation:
To simplify this, you would use the special product (a - b)^2 = a^2 - 2ab + b^2. We can correlate this with the given term so that,
a = 4w
and
b = 3
Now we just substitute into a^2 - 2ab + b^2
(4w)^2 - 2(4w)(3) + (3)^2
16w^2 - 24w + 9
Answer:
the independant variable is x
