Evaluate the expression when -3-6•5

-33

Step-by-step explanation:

because we use BODMAS so the multiplication comes first hence 5*-6 is -30 and add -3 to it makes it -33

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:

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
