Answer:
(4x - 5)(x + 2).
Step-by-step explanation:
4x^2 + 3x - 10
4 * 10 = -40
We need 2 numbers whose product is -40 and whose sum is +3.
Theses are = - 5 and + 8.
So we write:
4x^2 + 8x + -5x - 10
= 4x(x + 2) - 5(x + 2)
= (4x - 5)(x + 2).

you need to find how much they can make per hour so b can make 3.5 in 1 hr and n can make 4 and 8 is the equivalent that the amount of hrs it takes to make 60 leashes
• Move x to the other side
7y=21-3x
• Divide by 7
y = (21-3x)/7
Answer:
Step-by-step explanation:
Before we answer the problem, let's talk about what we know.
There are 4200 Adults, and 3/8 don't have children.
8/8 - 3/8 = 5/8 (Adults that do have children).
Note: 8/8 is the total of adults in lakeview.
Finally, you would take the number of adults at lakeview, and multiply it by the fraction of adults that do have children.
4200 x (5/8) = 2625
