5. Here are two copies of the same figure. Show two different ways for
dedylja [7]

The two different ways of finding the area are,
Case 1 = assume horizontal rectangles,
Case 2 = assume vertical rectangles.

<h3>What is a rectangle?</h3>

the rectangle is a four-sided polygon whose opposites sides are equal and has an angle of 90° between its sides.

Here,

case 1,
As shown in the image
Area = sum of horizontal rectangles
Area = 10 * 3 + 2 * 5 + 2 * 1
Area  = 30 + 10 + 2
Area = 42    

Case II,
As shown in right figure,
Area of the vertical rectangles
Area = 3 * 5 + 5 * 3 + 2 * 6
Area = 15 + 15 + 12
Area = 42
Here, the area in case 1 is equal to case 2.

Thus, the two different ways of finding the area have shown above.

Given : 11x – 6y = –1; x = 8
Natasha_Volkova [10]

Answer:

B. a. Given; b. Substitution Property; c. Subtraction Property of Equality; d. Division Property of Equality; e. Symmetric Property of Equality

Step-by-step explanation:

Given expression,

11x - 6y = -1; x = 8

By substituting x = 8,

11(8) - 6y = -1

88 - 6y =-1

By subtraction property of equality,

-6y = -89

Division property of equality,

y = \frac{89}{6}

By symmetric property of equality,

\frac{89}{6} = y
