Answer:

x = 15

Step-by-step explanation:

<u>Step 1:  Distribute</u>

3x - 5(x) - 5(2) = -40

3x - 5x - 10 = -40

<u>Step 2:  Combine like terms</u>

-2x - 10 = -40

<u>Step 3:  Add 10 to both sides</u>

-2x - 10 + 10 = -40 + 10

<u>Step 4:  Divide both side by -2</u>

-2x / -2 = -30 / -2

x = 15

" A projectile is launched in the air according to the equation h(t)= -16t^2 + 125t + 5. At what time does the projectile land?"
Vlad1618 [11]
"according to the equation is a sloppy description, and announces that whoever said it or wrote it doesn't really have a clue to what the equation means or what it's good for.

h (t) is the HEIGHT of the projectile above the ground at any time 't'. When the projectile hits the ground, h (t) is zero. Write that ! Then you have a quadratic equation that you can easily solve for 't'.

Answer:

The surface area of the composite figure is 1108 square inches.

Step-by-step explanation:

The surface area of the composite figure (A_{T}) is equal to the sum of external faces of the rectangular and triangular prisms, all measured in square inches:

A_{T} = 20\,in \times 12\,in + 2\times 5\,in \times 12\,in + 2\times 20\,in \times 5\,in  + 2\times 20\,in \times 11\,in + 2\times \frac{1}{2}\times 12\,in \times 9\,in

A_{T} = 1108\,in^{2}

The surface area of the composite figure is 1108 square inches.
