Answer:
y = 20.
Step-by-step explanation:
Distribute:


Add 18 to both sides:


Solve for y:


Rewrite it in the form a^2 - b^2, where a = 5x and b = 8
(5x)^2 - 8^2
Use the Difference of Squares; a^2 - b^2 = (a + b)(a - b)
<u>= C. (5x - 8)(5x + 8)</u>
Answer:
y = 3(x+7/6)² - 25/12
Step-by-step explanation:
Answer:
the rate at which the distance between the planes is changing is 825 each hour
Step-by-step explanation:
The computation of the rate at which the distance between the planes is changing is shown below
= Travelling one plane + travelling another plane
= 450 mph + 375 mph
= 825 mi each hour
Therefore the rate at which the distance between the planes is changing is 825 each hour
We simply applied the above formula so that the correct value could come
And, the same is to be considered
60 degrees because vertical angles are congruent if you move line y 5 degrees clockwise then you are adding 5+55=60 and since 1 and 3are congruent 3=60 degrees
