Answer:
No, they are not equivalent
Step-by-step explanation:
Answer:
This is NOT equivalent to 2b(b + 8).
Step-by-step explanation:
Start with -2/3(12b - 6 + 9b - 18). Simplify this. First, combine the like terms inside the set of parentheses:
(-2/3)(21b - 24)
Simplify this by applying the distributation property of multiplication:
-14b + 16
Finally, factor out 2: 2(-7b + 8)
This is NOT equivalent to 2b(b + 8).

Answer:
D: 8,100π in²
Step-by-step explanation:
The formula for area of a circle is
A = πr²
The radius is squared, so if the radius or a new circle is 6 times larger (multiplied by 6), the difference in area will be 36 times greater. So the area is
225π(36) = 8,100π
Answer:
1. 3/4 + 3/4 + 3/4 +3/4
2. 0.75 * 4
Step-by-step explanation:
1. add 3/4 four times
3/4 + 3/4 + 3/4 +3/4
2. You can turn 3/4 into a decimal. 3/4 =0.75
0.75 * 4
Area of a semicircle =
r² / 2
r= 5/2 = 2.5
So: A= 3.14 x 2.5² / 2 A = 9.8125 so rounding to the nearest hundredth is A=9.81
