Answer:
Step-by-step explanation:
Well.. First of all, the question says that we are working with a rectangle..
So, the rectangle has a length and width. I'll call them L and w.
Look at this phrase: " length that is one foot less than twice its width"
it means, in a algebraic language: L = 2w - 1
Let's analysis the next phrase: "it the area of the rectangle is 91 square feet"
So, A = 91 ft²
But you have to remember that the rectangle area is a product of L and w.
L x w = 91
They are the following equations that you could be used to solve the system of equations.
Now, you have a system of equations and I suggest you to solve it using the substituition method.
L = 2w - 1
L x w = 91
Answer:
15/100x 40= 6
Step-by-step explanation:
To find the perimeter of Lorenzo's patio, you need to understand that perimeter is a measurement of distance around a sided figure.
We know the side lengths are 12 feet, 14 feet, 12 feet, and 14 feet because it is a rectangle.
Add all these together to find the total distance around.
12 + 12 + 14 + 14 or (12 x 2) + (14 x 2) = 52 feet
The perimeter of Lorenzo's patio is 52 feet.
$12.6 -- 25% of 12.6 is exactly $3.15
I did this by taking 3.15 / 0.25
Answer:
10
Step-by-step explanation:
2[45/(11-8)^2]
=2[45/(3)^2]
=2[45/9]
=2[5]
=10
