The leather of marshalls rectangular poster is 2 times its width. if the perimeter is 24 inches, what is the area of the poster

Answers

Answer 1

Answer: Well, the perimeter is the rim of the rectangle and you can use the rim to find the area... but, First you have to find the length and the width
if the width is two times the height when you flip that you get that the height is half of the width
So first you find that half of 24 is 12... this is our width
Now, what is half of 12... 6, this is our height
simple math tells us that to find the area you multiply that height and the width
6 * 12 = 72
so the area of the poster is 72 inches

Given: x - 5 > -10. Choose the solution set.

{x | x R, x < -15}
{x | x R, x > -5}
{x | x R, x < 5}
{x | x R, x > 15}

Answers

Answer:

B. $\{x|x\text{ R},x>-5\}$

Step-by-step explanation:

We have been given an inequality. We are asked to choose the solution set for our given inequality.

$x-5>-10$

First of all, we will separate variable x on one side on inequality as:

$x-5+5>-10+5$

$x>-5$

Therefore, the solution for our given inequality are all values of x greater than $-5$ and option B is the correct choice.

It is the second one.Caus -10 +5 when it is brought to the other side.Thus x>-5

Answers

Answer:

Step-by-step explanation:

In the end, the used car would cost him more than the new car. This is because the insurance premium for a used car will generally be more than that of a new car. This is because the risks associated with a second-hand car are higher. This is due to the fact that that they are more likely to break down than new cars.
