Answer:

The mistake is that you are supposed to do the 15 - 4 first, getting 11, then applying the distributive property and multiplying 11 by 1x and 3.

The area of the entire figure below is 111 square unit.
Ivahew [28]

The striped rectangle has a total area of 69,375 cm².

<h3>How to calculate the area of the striped rectangle?</h3>

To find the area of the striped rectangle we must carry out the following procedures.

Find the area of each segment of the rectangle, that is, what is the area of each of the 24 squares that make up the rectangle, for that we divide the 111cm² of the total area into 24.

  • 111cm² ÷ 24 = 4.625cm²

According to the above, we infer that each square has an area of 4.625cm².

On the other hand, to find the area of the striped rectangle we must take into account that it is 5 squares long by 3 squares high, that is, its area is 15 squares.

  • 3 × 5 = 15

Finally, each square has an area of 4.625cm², so to find the total area of the striped area we must multiply the area of each square by the number of squares.

15 × 4.625cm² = 69.375cm²

What is the midpoint of the segment (1, -1) (4, -6)
Sophie [7]
When looking for the midpoint of a segment defined by two end points, the average of both coordinates are taken. Averaging the 2 x-coordinates give the new x-coordinate, and the same applies for the y-coordinate. This is shown below:

Midpoint = ( (1 + 4)/2 , (-1 + -6)/2 )
Midpoint = (2.5 , -3.5)

which ordered pairs are a solution to the question y=8× select all that apply (-1,-7)(2,16)(1,8)(-2,-6)​
abruzzese [7]

Answer:

(2,16) , (1, 8)

Step-by-step explanation:

(-1,-7), x = -1 and y = -7

plug in

y = 8x

-7 = 8 * -1

-7 = -8, false

(2,16), x=2 and y = 16

plug in

y= 8x

16 = 8 * 2

16 = 16, so it is a solution

(1,8), x = 1 and y = 8

plug in

y = 8x

8 = 8 * 1

8 =8 , so it is a solution

(-2,-6), x = -2, y = -6

plug in

y = 8x

-6 = -2 * 8

-6 = -16, false
