I really need help lol

For the expression if they don't want you to include the variables then I would write 3.14(6 + 4) or 3.14(2*3+2²). For the surface area, your answer is 31.4 units.

Step-by-step explanation:

If r = 2 and s = 3, then just plug them into the equation 3.14(rs + r²)

3.14(2*3+2²)

= 3.14(6+4)

=3.14(10)

=31.4 units for the Surface Area

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

-9
