Answer:

x = ± 13

Step-by-step explanation:

Given

x² = 169 ( take the square root of both sides )

x = ± $\sqrt{169}$ = ± 13

Since 13 × 13 = 169 and - 13× - 13 = 169

The average speed of a car on a stretch of interstate is 70 miles per hour. Convert this rate to feet per second.

polet [3.4K]

Answer:

<h3>102. 66 feet / Second</h3>

Step-by-step explanation:

To do conversion change miles into feet and hour into second.

One foot is 5280 feet

And an hour is 3600sec

70 miles / Hour

70 * 5280feet / 3600 second

369600 feet / 3600seconds

Then simplify

102. 66 feet / Second
