Answer:
Area: 28 square ft
Perimeter: 22 ft
Step-by-step explanation:
To find the area:
A=Lw
A is area, L is length, w is width
A=4*7
A=28
The area is 28 <em>square</em> feet
To find the perimeter:
P=2L+2w
P=2(7)+2(4)
P=14+8
P=22
The perimeter is 22 feet.

The absolute value of a number is the distance the number is from zero on the number line. Only one number is 0 units from 0. It is zero. For all other distances, there are always two numbers. Example: The two numbers a distance of 1 unit from zero are -1 and 1. Example: The two numbers a distance of 4.5 units from zero are -4.5 and 4.5.
In your case, the two numbers a distance of 1.75 units from zero are -1.75 and 1.75. Find -1.75 between -1.5 and -2 and place a dot there. Find 1.75 between 1.5 and 2 and place a dot there.

Answer:
B
Step-by-step explanation:
Answer:
She made an error when using the zero pair.
Step-by-step explanation:
In step 2, Carianne added 4 to the right side and subtracted 4 on the left side, which is completely changing the equation. By definition, your zero pair must have a difference of zero. She need to add 4 to both sides to continue; when manipulating algebra you need to do the same thing to both sides of an equation, otherwise you're just changing the equation.
