Answer:
x+10-y
Step-by-step explanation:
i'm not 100% sure about this response, but i'd assume the answer is like this for the following reasons:
alex is x years old, and 10 years have passed, meaning 10 years are added onto his age (x+10). addison is still the same amount of years apart from him in age, so you subtract y from that (x+10-y).
<span>The roots of a quadratic equation ax²+bx+c=0 can be determined by calculating the discriminant Δ=b²-4ac.
If Δ>0, there are two distinct real solutions.
If Δ=0, there is one real solution.
If Δ<0, there are no real solutions and two complex solutions.
Δ>0, so there are two distinct real solutions. The answer is A.

A. first the find the are of the top side. to get the area of a circle you do radius squared times pi. The radius is half the diameter so 5 squared times ok equals 78.5
Then times that by the length, 21 times 78.5 equals 1648.5
b. first square the radius to get 400, then times that by 4 to get 1600. after that multiply that by ok to get 5026.5
