Answer:

The number is 19

Step-by-step explanation:

7 less than a number = x - 7

2x - x - 7 = 12

Subtract x from 2x

x - 7 = 12

Add 7 to both sides of the equation

x = 19

The number is 19

just kick the 3 to the other side, so a negative 3 would become a positive 3:

x= 10 + 3

x= 13

djyliett [7]

Answer:

x= 6 ± √31

Step-by-step explanation:

x^2-12x=-5

x^2 -12x +36= -5 +36

(x -6)^2= 31

√(x -6)^2= ±√31

(x-6)= ±√31

x= 6 ± √31

Find the surface area of the composite figure.

zhuklara [117]

Answer:

438.97 cm²

Step-by-step explanation:

To find the surface area, we break up the figure into two pieces(blue and yellow) and then add them together.

SA = 2(w · l + h · l + h · w)

2 · (6 · 16 + 4 · 16 + 4 · 6)

368 cm²

70.97 cm² + 368 cm²

438.97 cm²
