Answer:
X=18
Step-by-step explanation:
Here you have to use cross multiplication
Using the area of a rectangle, it is found that her patio should have a width of 12 feet and a length of 27 feet.
<h3>What is the area of a rectangle?</h3>
The area of a rectangle of length l and width w is given by:
A = lw.
In this problem:
- She has enough tiles to cover 324 square feet, hence A = 324.
- She wants the length of the patio to be 15 feet longer than the width, hence l = 15 + w.
Thus:
324 = w(15 + w)
w^2 + 15w - 324 = 0
w = -27 or w = 12.
We take the positive value, hence l = 15 + w = 15 + 12 = 27 feet.
The dimensions should be a width of 12 feet and a length of 27 feet.

Answer:
function not provided
Step-by-step explanation:
y = mx +b is slope intercept formula
b is the y intercept and m is the slope (rise/run) ,
if slope is multiplied by 1/2 then multiply the m value in original function by 1/2
if 3 is added to the y intercept value then add 3 to the b value in original function.
then compare to plots given,
y intercept is where the line crosses the y axis
slope is how much the line goes up over how much it goes to the side
Answer:
slope = -
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (3, 2) and (x₂, y₂ ) = (5, - 1)
m = = = -
