gladu [14]

Answer:

Part 1) 2x^{2}-32=0----> (-4,4)

Part 2) 4x^{2}-100=0----> (-5,5)

Part 3) x^{2}-55=9----> (-8,8)

Part 4) x^{2}-140=-19----> (-11,11)

Part 5) 2x^{2}-18=0----> (-3,3)

see the attached figure

Step-by-step explanation:

Solve each quadratic equation

Part 1) we have

2x^{2}-32=0

Adds 32 both sides

2x^{2}=32

Divide by 2 both sides

x^{2}=16

take square root both sides

x=\pm4

therefore

The solutions are (-4,4)

Part 2) we have

4x^{2}-100=0

Adds 100 both sides

4x^{2}=100

Divide by 4 both sides

x^{2}=25

take square root both sides

x=\pm5

therefore

The solutions are (-5,5)

Part 3) we have

x^{2}-55=9

Adds 55 both sides

x^{2}=9+55

x^{2}=64

take square root both sides

x=\pm8

therefore

The solutions are (-8,8)

Part 4) we have

x^{2}-140=-19

Adds 140 both sides

x^{2}=-19+140  

x^{2}=121

take square root both sides

x=\pm11

therefore

The solutions are (-11,11)  

Part 5) we have

2x^{2}-18=0

Adds 18 both sides

2x^{2}=18

Divide by 2 both sides

x^{2}=9

take square root both sides

x=\pm3

therefore

The solutions are (-3,3)

elena55 [62]
I got area=41.7 m

Step by step:
Find A; 6x4 =24
Find B; you have to subtract 2 from 3.8 to find the length of the dashed line. 1.8x3.5=6.3
Find C; 3.8x3=11.4.
Add together; 11.4+6.3+27=41.7

The area of the given parallelogram is 120.

Step-by-step explanation:

Step 1:

The parameters needed to determine the area of a parallelogram are the base length and height.

The base length of this parallelogram is 15 inches while its height is 8 inches.

The area of a rectangle is determined by multiplying the base length with the height.

Step 2:

The area of the parallelogram = (b)(h).

Here the base length is 15 inches and the height is 8 inches.

The area of the parallelogram =(15)(8) = 120.

So the area of the given parallelogram is 120.
