Answer:
A:
Step-by-step explanation:
We are given that a metal sheet which is required to make square -shaped traffic sign.
We are given that a square shaped traffic sign is shown with length of on side labeled as x+1.
We have to find an expression which is equivalent to area of metal sheet used in square shaped traffic sign
Length of square shaped traffic sign=
We know that area of square =
Therefore, area of metal sheet used in square shaped traffic sign=
Hence, option A is true.

Answer:
Her proportion does not have corresponding parts in the same position.
Step-by-step explanation:
Sharon is drawing up a plan for building a reduced Eiffel Tower on her backyard patio. She has room to make a base of 5 feet. Her work is shown below.
What was Sharon’s error in finding the missing height measurement for her reduced tower?
Her proportion does not have corresponding parts in the same position.
For cross products, she needed to multiply 1050(328) and 5(x).
She needed to divide both sides by 1640, instead of 1050.
She needed to round down to 1.5 feet.
Height : base = 1,050 : 328
She has room to make a base of 5 feet.
Height : base = x : 5
1,050 : 328 = x : 5
1,050 / 328 = x / 5
Cross product
1,050 * 5 = 328 * x
5,250 = 328x
Divide both sides by 328
x = 5250 / 328
= 16.006
Approximately 16
