Answer:
5b(2 - 5b²)
Step-by-step explanation:
Simply take out GCFs to factor out the expression:
Step 1: Factor out GCF of 5
5(2b - 5b³)
Step 2: Factor out GCF of <em>b</em>
5b(2 - 5b²)
We can't factor the quadratic any further so that is our final answer.

Step 1
<u>Find the total area</u>
Total area=(1,150,000/18,075)=63.62 square kilometer
The area of a circle is equal to

therefore
the answer is

Answer:
Given that x=5, when we substitute in 5 for 2x + 3 = 13, the equation will turn out to be true.
Step-by-step explanation:
2x + 3 = 13 x=5
2(5)+3=13
10+3=13
13=13
Answer:
It's choice B.
Step-by-step explanation:
Let's look the one you have chosen (A):
f(x) = x - 2/ 7 + 8
x-2 / 7 = f(x) - 8
x- 2 = 7(f(x) - 8)
x = 7(f(x) - 8) + 2
The inverse)= 7(x - 8) + 2
So it's not A.
B. f(x) = 5(x/4) - 3
5x / 4 = f(x) + 3
5x = 4(f(x) + 3)
x = 4(f(x) + 3 / 5
So the inverse is 4(x + 3) / 5
So it is B.
