Step-by-step explanation:
It is given that,
The height of the sail on a boat is 7 feet less than 3 times the length of its base.
Let the length of the base is x.
ATQ,
Height = (3x-7)
Area of the sail is 68 square feet.
Formula for area is given by :
x = 8 feet and x = -3.73 feet
So, length is 8 feet
Height is 3(8)-7 = 17 feet.
So, its height and the length of the base is 17 feet and 8 feet respectively.
Answer:
C
Step-by-step explanation:
If a number is to the power of a negative number, then it is just that number's reciprocal: e.g. y⁻ˣ =
Therefore, m⁻² will be m² in the denominator, as n⁻³ will be n³ in the numerator.
That will look like .
So, that is C.
Answer:
Step-by-step explanation:
Given:
To solve this equation, we need to isolate on one side of the equation algebraically. I see that we have like terms, but they are on opposite sides of the equal sign. Let's add
to both sides.
To isolate x, divide both sides by 7.
