Answer:
C
Step-by-step explanation:
we have to solve the associated equation:
(x+5)(2x-8) = 0
a product is equal to 0 if at least one of its factors is equal to 0
so we can solve this two equations
x + 5 = 0 x = -5
2x - 8 = 0. x-4 = 0 x = 4
The number of boys signed up to play basketball this year is 560.
Given that, the number of boys who played basketball last year = 320.
We need to find the number of boys signed up to play basketball this year.
<h3>What is a percentage?</h3>
In mathematics, a percentage is a number or ratio expressed as a fraction of 100.
Now, the number of boys signed up to play basketball this year = 175 per cent of what it was last year.
So, the number of boys signed up to play basketball this year = 175% of 320
![=\frac{175}{10} \times 320=1.75 \times 320=560](https://tex.z-dn.net/?f=%3D%5Cfrac%7B175%7D%7B10%7D%20%5Ctimes%20320%3D1.75%20%5Ctimes%20320%3D560)
Therefore, the number of boys signed up to play basketball this year is 560.
