we are given

(5.2 − 4.5) − 5.5 + 4.8

we will check each steps

we always use PEMDAS rule

P: Parenthesis

E: Exponent

M: Multiplication

D: Division

A: Addition

S: Subtraction

Step 1: (5.2 − 4.5) − 5.5 + 4.8

This is same as original

so, this is TRUE

Step 2: 5.2 + (− 4.5 − 5.5) + 4.8 (identity property)

we know that

identity property is

0+a=a

so, this is FALSE

Step 3: 5.2 − 10 + 4.8

this is TRUE

Step 4: 5.2 + 4.8 − 10 (commutative property)

we know that commutative property is

a+b=b+a

so, this is TRUE

Step 5:

10 − 10 = 0

this is TRUE

Find the area of this trapezoid. Be sure to include the correct unit in your answer.
Sedaia [141]

Answer:

88 sq.in

Step-by-step explanation:

<u>Area of trapezoid = 1/2 (b1 +b2) x h</u>

<u>In this figure:</u>

b1 = 18 in, b2 = 4 in, h = 8 in

<u>So:</u>

A = 1/2 (18 + 4) x 8

A = 1/2 (22) x 8

A = 11 x 8

A = <u>88 sq.in</u>

A rectangular parking lot has a perimeter of 232 feet. The length of the parking lot is 36 feet less than the width. Find the le
Ne4ueva [31]

Answer:

<u>The rectangular parking lot has a width of 76 feet and a length of 40 feet</u>

Step-by-step explanation:

Let's find the length and the width of the rectangular parking lot, this way:

Perimeter = 232 feet

Perimeter = 2 Length + 2 Width

Length = Width - 36 feet

Now, substituting, we have:

2 (Width - 36) + 2 Width = 232

2 Width - 72 + 2 Width = 232

4 Width = 232 + 72

4 Width = 304

Width = 304/4 = 76 feet

Length = 76 - 36 = 40 feet

<u>The rectangular parking lot has a width of 76 feet and a length of 40 feet</u>
