Multiply.
sergij07 [2.7K]

Answer:

D) 2x² + 4x - 30

Step-by-step explanation:

Follow the FOIL method:

FOIL =

First

Outside

Inside

Last

...and is the order you multiply to solve:

(x + 5)(2x - 6) =

(x)(2x) = 2x²

(x)(-6) = -6x

(5)(2x) = 10x

(5)(-6) = -30

Combine like terms. Simplify:

2x² -6x + 10x - 30 = 2x² (-6x + 10x) - 30 = 2x² + 4x - 30

2x² + 4x - 30 is your answer.

An object has been thrown straight up into the air. The formula h = vt - 16t^2 gives the height of the object above the ground a
Oxana [17]

Answer:

8 seconds.

Step-by-step explanation:

To solve this question, we need to find the time, t, when h = 0, that is, when the height of the object above the ground is 0 feet.

Substituting v = 128 feet per second and h = 0 gives  the quadratic:

0 = 128t - 16t^{2}

Since 128 is divisible by 16, it can be reduced to 0 = 16(8t - t^{2}).

We must now solve for t.

We can easily see that one answer to the equation is 0,

8(0) - (0)^{2} = 0 (we need not concern ourselves with the 16 outside of the parenthesis as in the equation above, since 16 multiplied by 0 is 0). However this is the time the object is released into the air.

The second answer, t = 8 is also easy to see by inspection:

8(8) - (8)^{2} = 0.

Therefore the object lands 8 seconds after it is thrown.
