Answer:
d. 4x^2-20x-25
Step-by-step explanation:
So, we have to multiply (2x-5) by itself. That gives:
(2x-5) (2x-5) = 2x (2x-5) - 5 (2x-5) = 4x² - 10x -10x + 25
so, the correct answer is 4x² - 20x + 25
It's just important to multiply each component carefully by using the distributive property.

for every member to get a shirt you would need to order 9 packages of shirt (because 5 times 9 is 45) and for caps the minimum to order would be 15 packages of caps
explanation

15 is the total packages of hats needed to order
for shirt 45 divided by 5 is 9
9 is the total packages of shirts needed to order
