Answer: choice A or (-25)(-25)=625
Step-by-step explanation:
its choice A because a negative times a negative equals a positive :)
Answer: 98 degrees
Step-by-step explanation:
For this, we will be using the quadratic formula, which is
, with a=x^2 coefficient, b=x coefficient, and c = constant. Our equation will look like this: 
Firstly, solve the multiplications and the exponents: 
Next, do the addition: 
Next, your equation will be split into two:
. Solve them separately, and your answer will be
Answer is 41 miles total
Equation is (2miles x 7) + (3 miles x 9) = total
14 + 27 = total miles
41 = total miles
