Hello from MrBillDoesMath!
Answer:
12a + 18b
Discussion:
The question asks us to calculate
24a + 10 b - (12a - 8b) => (combine common terms)
(24a - 12a) + ( 10b + 8b) => ( as - (-8b) = + 8b)
12a + 18b

Answer:
(a) So the top of the hill is 365 feet above sea level.
(b) Checkpoint 5 is 185 feet higher than checkpoint 2.
Step-by-step explanation:
<u>Solution for (a):</u>
<u />
Checkpoint 2 is -218 feet above sea level.
The top of a hill rises 583 feet above Checkpoint 2.
The altitude of the top of the hill = -218 + 583 = 365
So the top of the hill is 365 feet above sea level.
<u>Solution for (b):</u>
<u />
Checkpoint 2 is -218 feet above sea level.
Checkpoint 5 is -33 feet above sea level.
Checkpoint 5 is -33 - -218 = 185 feet higher than checkpoint 2.
Answer:
because it can be written in the <u>form</u><u> </u>of p/q
Where p and q are integers, and q is <u>not</u> equal to zero.
Find thy radius.
Thy radius is 7.25 (D / 2 = R)
Thy formula for area is A = (pi)r^2
Substitute and Solve
A = (pi)r^2
= (pi)(7.25)^2
= (pi)(52.5625)
= 165.04625
Therefore, the area is about 165.
