So, 30 is the perimeter. We are told the table is twice as long as it is wide.
So, we have think of 2 numbers, one being twice as big than the other. So, it is a rectangle The two number represents the length and the width. To find the perimeter we add all the lengths and the widths. Since the pool table is a rectangle we have two lengths and two widths.
So,
the tow numbers be 10 and 5. 5 is half of 10 and, when multiplied by 2 it is 10. So just to make sure the numbers 5 and 10 work out lets do a calculation.
So,
10+5+10+5 = 30feet. This proves that the sides are these two numbers.
Lets solve the equation and see the steps so it is easier.
x/2 - 8 = 14
Add eight to both sides of the equation to get x/2 alone.
x/2 - 8 + 8 = 14 + 8
x/2 = 22
Multiply both sides by two to get x alone.
x/2 • 2 = 22 • 2
x = 44
Now we see the steps we made. Lets look at the choices. Your answer is the third choice. I hope this helps!
Answer:
42 cubic units
Step-by-step explanation:
7 x 3 x 2 = 21 x 2 = 42
<h3>
Answer: Choice A. |w - q|</h3>
Let's say for example that w = 10 and q = 7. This means the distance between these values is w-q = 10-7 = 3. This is the distance between w and q.
Now let's make q larger. If w = 12 and q = 20, then w-q = 12-20 = -8 assuming we subtract in the same order. We use absolute value bars to ensure the result is positive. So instead we say
|w - q| = |12 - 20| = | -8 | = 8
Distance is never negative.
The correct answer is negative
