Riley was determined to be on the basketball team. He started practicing for 40 minutes on the first day, and then increased his practice time by 20 minutes on each subsequent day. With that pattern, how many total minutes will he have practiced in 25 days?

A) 7,000 minutes

B) 6,500 minutes

C) 14,000 minutes

D) 13,000 minutes

Step-by-step explanation:

If each day he increases his practice time by 20 mins then after 25 days his total practice time would be increased by 25*20 mins which is 500 mins then you add the first 40 mins you get 540. The you can figuire out the rest from there.

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!
