Answer:

{x\ x e U and x has a negative square root} is an empty set.

Step-by-step explanation:

If x e U, x is a negative real number, and they don't have a square root (they don't have even roots). Their square roots are complex numbers, not real ones.

JulijaS [17]

Answer:

42.06 ft²

Step-by-step explanation:

          2 sides = 2(2.7 ft × 3.2 ft) = 2 × 8.64 ft² =   17.28 ft²

 Front + back =  2(2.1 ft × 3.2 ft) = 2 × 6.72 ft² =   13.44 ft²

Top + bottom =   2(2.1 ft × 2.7 ft) = 2 × 5.67 ft² =   <u>11.34 ft² </u>

                                                         Total area = 42.06 ft²

5=1/2x - 3 please help me out
liq [111]

Answer:

x = 16

Step-by-step explanation:

5 = 1/2(x) - 3

Add 3 to both sides.

8 = 1/2(x)

Rewrite for clarity.

1/2(x) = 8

x/2 = 8

Multiply both sides by 2.

x = 16.

Proof:

5 = 1/2(x) - 3

Substitute variable.

5 = 1/2(16) - 3

Multiply 1/2 and 16.

5 = 8 - 3

Subtract 3 from 8.

5 = 5
