Answer: 49
Step-by-Step Explanation:
As we can see, we have been given a negative exponent for “x”. Hence we have to take the reciprocal which would be x squared.
Therefore, x = 7
= x^2 = 7 * 7
= 49
Answer:

All you have to do to solve this is subtract 18 from 25
Answer:
Step-by-step explanation:
Let
x ----> the number of minutes
y ----> the amount of fuel in gallons
we know that
The linear equation in slope intercept form is equal to
where
m is the unit rate or slope
b is the y-intercept or initial value
we have that
The unit rate or slope is equal to
----> initial value (value of y when the value of x is equal to zero)
substitute
The perimeter is D because you have to add all the sides up. 2 + 2 and 3 plus 3 equals 10x and then 8 + 8 and 2 + 2 equals 20 so 10x- 20.
