So I know 5 + 6(2x + 3) - 2x = 10x + 23. But how do I show my work?

Step-by-step explanation:

5+6 (2x + 3) -2x = 10x + 23

5 + 6(2x-3) -2x = 10x+23

10x + 23 = 10x + 23

-23 -23

10x = 10x

-10x -10x

0 = 0

Or if you divide will be

10x = 10x / ÷10

X= 1

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
