Answer:

A. ( x + 3 )² = 25

Step-by-step explanation:

2x² + 12x = 32

2(x² + 6x) = 32

x² + 6x + 9 = 16 + 9              [ addition of 9 from both sides ]

( x + 3 )² = 25

A projectile is fired directly upward. The compound inequality 89 – 9.8t < 10.6 or 89 – 9.8t > 20.4 represents a projectil
Tom [10]

Given compound inequality 89 – 9.8t < 10.6 or 89 – 9.8t > 20.4.

Let us solve them one by one.

89 – 9.8t < 10.6

Subtracting 89 from both sides, we get

89-89 – 9.8t < 10.6 - 89

-9.8t < -78.4

Dividing both sides by -9.8, we get

t > 8.

<em>Note: Inequality sign get flip on dividing both side by a negative number.</em>

89 – 9.8t > 20.4

Subtracting 89 from both sides, we get

89-89 – 9.8t < 20.4 - 89

-9.8 t < - 68.6.

Dividing both sides by -9.8, we get

t < 7

<em>Note: Inequality sign get flip on dividing both side by a negative number.</em>

<h3><em> The solution to the inequality 89 – 9.8t < 10.6 is </em>t > 8. </h3><h3> The solution to the inequality 89 – 9.8t > 20.4 is t < 7.</h3>

When the projectile hits the ground:

89 – 9.8t = 0

Subtracting 89 from both sides, we get

89 - 89 – 9.8t = 0 -89.

-9.8t = -89.

Dividing both sides by 9.8, we get

<h3>to the nearest whole second  t is about 9 seconds.</h3><h3>Therefore, variable solution set is {t < 7, t > 8, t = 9}.</h3><h3 />

PLS HELP WITH THE QUESTION IN THE PICTURE!!!
Ksivusya [100]

Answer:

D

Step-by-step explanation:

Interesting question.  The wording is a bit awkward. I think you have to assume the base is a square and each succeeding base is also a square.

So the first thing to do is to add the bases together.

30*30 + 23*23 + 16*16 + 9*9

Don't add these -- not yet.

Now take the height into consideration

6 *(30*30 + 23*23 + 16*16 + 9*9)

The point is that you only have to multiply by 6 once.

6*(900 +  529 + 256 + 81)

6*(1766)

10596 cubic inches

The answer is D
