Evaluate the following expression: 8x - 6 - 7y + 3 use x=3 and y=6

-27

Step-by-step explanation:

8x - 6 - 7y + 3

X = 3 Y = 6

8(3) - 6 - 7(6) + 3

8 x 3 = 24

7 x 6 = 42

24 - 6 - (42 + 3)

(24 - 6) - 45

18 - 45 = -27

pi x^2

step-by-step explanation:

pi times x squared

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
