<h3>Answer:  D)  rectangle</h3>

===============================================================

Explanation:

Since this is a parallelogram, the top and bottom sides are parallel. This in turn means the bottom left angle is 90 degrees. Recall that same side interior angles are supplementary when we have parallel lines. So if x was the bottom left angle, then 90+x = 180 solves to x = 90.

In short, the bottom left corner is a right angle.

Through similar steps, we can prove the other remaining interior angles are also 90 degrees each.

This figure is a <u>rectangle</u> because all four angles are 90 degrees.

We unfortunately don't have any info about the sides, so we don't know if the figure is a square or rhombus. If all four sides were the same length, then we have a rhombus. A figure being a rectangle and a rhombus means that it is also a square.

The model represents an equation. What value of x makes the equation true?
kirill [66]

Answer:

<h3>B. 9/4</h3>

Step-by-step explanation:

According to the diagram, there are 5 x's in and 8 of negative 1 in the left hand side of the equation. This is represented mathematically as;

= 5x+8(-1)

= 5x - 8 .............. 1

In the right hand side, there are 3 of -x's and 1 in 10 places. This is also expressed as;

= -3x+1(10)

=  -3x+10 ............ 2

Equate 1 and 2 and find x

5x-8 = -3x+10

add 7 to both sides

5x-8+8 = -3x+10+8

5x = -3x+18

add 3x from both sides

5x+3x = -3x+18+3x

8x = 18

x = 18/8

x = 9/4

Hence the value of x that makes the equation true is 9/4

Sissy wants to enlarge a picture of a princess so that she can put it on the wall in her daughter’s room. What will be the area
alisha [4.7K]

Answer:

= 486 in²

Step-by-step explanation:

Linear scale factor = Image distance/object distance

Therefore; Linear scale factor = OL'/OL

                                                 = 54/ 12

                                                 = 9/2

Area scale factor is equivalent to the square of linear scale factor

Thus;

Area scale factor = (9/2)²

                             = 81/4

Hence; 81/4 = Area of larger rectangle/Area of smaller rectangle

Area of the smaller rectangle = 4 ×6 = 24 in²

Therefore;

Area of enlarged or larger pic = 81/4× 24

                                                  <u>= 486 in²</u>

Solve using substitution<br><br> y=1/2x<br> x+4y=18
Aleks [24]

Answer:

The solution set is (6,3)

Step-by-step explanation:

Begin by multiplying equation 1 by 2. You'll see why in a moment

2y = 2*(1/2) x

2y = x

Substitute this value into equation 2.

2y + 4y = 18                  Combine like terms on the left

6y = 18                          Divide both sides by 6

6y/6 = 18/6                    Do the division

y = 3

To solve for x just use the top equation

y = 1/2x

3 = 1/2x                          Multiply by 2

3*2 = x

x = 6
