The triangle below is equilateral. Find the length of side x in simplest radical form with a rational denominator.

STatiana [176]

As the triangle is equilateral, the height is also the median.

As the median cut the side in two equal halve, and one of this half is 9, then the side is 18.

As the triangle is equilateral, every side is the same measure, so x = 18

How can you use factoring to solve these three problems?

torisob [31]

You're meant to make one side of the equation equal 0.
For example, the first problem is $2k x^{2}$ + 9k = -7
You'd add 7 to both sides, leaving you with $2k x^{2}$ + 9k +7 =0
And I assume you know how to factor??

Complete Question

Peyton is a sprinter who can run the 40-yard dash in 4.5 seconds. He converts his speed into miles per hour, as shown below.

Which ratio is incorrectly written?

40 yd/4.5 sec • 3 ft/1 yd • 5280ft/1 mile • 60 sec/1 min • 60 min/1 hr

Answer:

5280ft/1 mile is the incorrect ratio

Hence, 40-yard dash in 4.5 seconds = 18.2 miles per hour(mile/hr)

Step-by-step explanation:

We are to convert 40 yards per 45 seconds to Mile per hour.

We are given the following conversion ratios:

40 yd/4.5 sec • 3 ft/1 yd • 5280ft/1 mile • 60 sec/1 min • 60 min/1 hr

The incorrect ratio is 5280ft/1 mile .

It should have been written as 1 mile/5280 ft.

Hence,

40 yd/4.5 sec • 3 ft/1 yd • 1 mile/5280ft• 60 sec/1 min • 60 min/1 hr

= 432000mile/23700 hr

= 18.181818182 mile/hr

Approximately= 18.2mile/hr
