State the value of the discriminant then determine the number of real roots of the equation. -8w^2=-(11w-7) a)-110, 2 real roots b)93, 2 real roots c)-103, 0 real roots d)235,2 real roots

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

40 x 50 = 2000
