Answer:

yes, but there is a better way

Step-by-step explanation:

instead of multiplying x+3 on both sides, I would instead subtract 2 on both sides. If you do this, it would be easier to write this equation in standard form and find the intervals.

Gena attached a dog ramp to her sofa, which allows her oldest dog to easily climb onto a seat cushion. The ramp is 55 inches lon

matrenka [14]

The distance from the base of the ramp to the base of the sofa rounded to the nearest tenth is 47.3 inches.

Explanation

According to the diagram, length of the ramp is, $AC= 55$ inches. The top of the seat cushion is 28 inches above the floor. That means, $BC=28$ inches

We need to find the distance from the base of the ramp to the base of the sofa which is $AB$

In right angle triangle $ABC$ , using Pythagorean theorem...

$AC^2 = AB^2 + BC^2\\ \\ (55)^2= AB^2 + (28)^2 \\ \\ AB^2 = (55)^2 - (28)^2 \\ \\ AB^2 = 3025 - 784\\ \\ AB^2 = 2241\\ \\ AB = \sqrt{2241}= 47.3$

So, the distance from the base of the ramp to the base of the sofa rounded to the nearest tenth is 47.3 inches.
