The coefficient of b (that is, 2) divides into 2b and also into 8, so it is a factor (a value that is multiplied by another value to produce a term in an expression)
Answer:
n=15
Step-by-step explanation:
subtract 8 from both sides to get 3n=45
divide both sides by 3 to solve for n to get n=15
Answer

Solution
Simplify both sides of the equation.

We are left with d = 4+
Add

Hence, d = 
Answer: A is the right angle
Step-by-step explanation:
a. 20^2 + 15^2 = 25^2
400 + 225 = 625
625 = 625

Answer:
Circle 1 = 24 pi in² = 452.2 in²
Circle 2 = 706.5 in²
Circle 3 = 271.6 in²
Step-by-step explanation:
In order to find the Diameter of a circle, you have to multiply the radius by 2. According to circle 1, 12in (radius) multiplied by 2 gets you 24 pi in².
In order to find the area, you multiply the radius² and then multiply it by pi or 3.14.
Is green the circumference or the diameter??? Had a little bit of confusion in that part, but I gave you the area only for Circle 2 and 3. For circle 1 I found the diameter (24 pi in²) and the area.
