Answer:
The answer is below
Step-by-step explanation:
We are asked to find the perimeter of triangle CDE. The perimeter of a shape is simply the sum of all its sides, hence:
Perimeter of tiangle CDE = |CD| + |DE| + |CE|
Given that C(4, -1), D(4, -5), E(2, -3).
The distance between two points is given as:
Therefore the lengths of the triangle are:
Perimeter of CDE = 4 + 2.83 + 2.83 = 9.66 units
Expression for the number of tiles Bruce used : <u>5x+2</u>
Expression for the number of tiles Felicia used : <u>5x + 5</u>
<h3>Further Explanation </h3>One variable linear equation is an equation that has a variable and the exponent number is one.
Can be stated in the form:
or
ax + b = c, where a, b, and c are constants, x is a variable
We complete the introduction for the task
Bruce retiled his kitchen. Originally, he bought three boxes of tile with the same number of tiles in each. He ran out of tile and had to go back to get three extra boxes of tile. However, he only used two tiles from the last box to finish the job.
Felicia also retiled her kitchen. She bought five boxes of tile with the same number of tiles that were in each as Bruce’s boxes. She also ran out of tile. She had to go back to the store and get an extra five tiles to finish the job.
We can translate those in to expression of One variable linear equation (x = number of tiles)
He bought three boxes ⇒ 3x
He only used two tiles from the last box ⇒ 2x + 2
Total tiles of Bruce used : 3x+2x+2 = 5x+2
She bought five boxes ⇒ 5x
She get an extra five tiles to finish the job. ⇒ 5 tiles
Total tiles of Felicia used : 5x+5
