Find the distance driven, if you drive at 60 mph for 3 1/2 hours. Round to the nearest whole mile.

blsea [12.9K]

The answer is <span>C. 210 mi
</span>
The velocity (v) is distance (d) divided by time (t):
v = d/t

v = 60 mph
t = 3 1/2 h = 3.5 h
d = ?

d = v * t
d = 60 * 3.5 = 210 mi

Step by step PLEASE!!!

blondinia [14]

F(x) = 3x^2+6x-2

= 3(x^2+2x-2/3)
= 3(x^2 +2x + 1 - 1 - 2/3)
= 3((x+1)^2 - 1 - 2/3)
= 3((x+1)^2 -5/3))
= 3(x+1)^2 - 5

So our function is in the form:

f(x) = 3(x+1)^2 - 5
where a = 3, h = -1, k = -5

A number divided by 6 minus -3 equals 12

liberstina [14]

Let the number be x.

Therefore, by the problem

x/6-(-3) = 12

or, x/6+3 = 12

or, x/6 = 12-3

or, x/6 = 9

or, x = 9 × 6

or, x = 54

The number is 54.

What is the answer to 21=(x+3)2

IceJOKER [234]

First, distribute 2 to the (x+3) to get:
21 = 2x+6
subtract 6 from both sides to get:
15 = 2x
Finally, we divide both sides by 2 to simplify x to:
x = 7.5 (OR) x = $7 \frac{1}{2}$
(Just so you know, if you pick a brainliest answer, both you and the person who got the brainliest answer get some points.
