Answer 2

From the given options, only x² - 4x +4 and x² +10x +25 are perfect square trinomials. The correct options are the third and forth options - x² - 4x +4 and x² +10x +25

Determining perfect square trinomials

Recal that,

An expression is a perfect square trinomial if it takes the form ax² + bx + c and satisfies the condition b² = 4ac

For x² -9

a = 1, b = 0, c = -9

0² ≠ 4(1)(-9)

0 ≠ -36

∴ x² - 9 is NOT a perfect square trinomial

For x² - 100

a = 1, b = 0, c = -100

0² ≠ 4(1)(-100)

0 ≠ -400

∴ x² - 100 is NOT a perfect square trinomial

For x² -4x +4

a = 1, b = -4, c = 4

(-4)² = 4(1)(4)

16 = 16

x² - 4x +4 is a perfect square trinomial

For x² +10x +25

a = 1, b = 10, c = 25

(10)² = 4(1)(25)

100 = 100

x² +10x +25 is a perfect square trinomial

For x² +15x +36

a = 1, b = 15, c = 36

(15)² ≠ 4(1)(36)

225 144

∴ x² - 4x +4 is a NOT perfect square trinomial

Hence, from the given options, only x² - 4x +4 and x² +10x +25 are perfect square trinomials. The correct options are the third and forth options - x² - 4x +4 and x² +10x +25

Gershon lives 3 10 mile from the soccer fields. How far does Gershon walk if he walks from home to the soccer fields and back home? How many miles did he walk

Answers

Answer:

Gershon walked 620 mile

Step-by-step explanation:

From the question,

Gershon lives 310 mile from the soccer fields,

This means the distance from where Gershon lives to the soccer fields is 310 mile.

Likewise, the distance from the soccer fields to where Gershon lives his as well 310 mile.

So, if Gershon walks from his home to the soccer fields, he will cover a distance of 310 mile.

Then, if Gershon walks back home from the soccer fields, he will cover another distance of 310 mile.

Now, To determine how many miles he walked,

Total number of miles Gershon walked = The distance from where Gershon lives to the soccer fields + The distance from the soccer fields to where Gershon lives

Hence, Total number of miles Gershon walked = 310 mile + 310 mile

Total number of miles Gershon walked = 620 mile

Hence, Gershon walked 620 mile

Find the slope of the line passing through the points (-18, -5) and (-19, -13)​

Answers

Answer:

Let (-18, -5) be (x1,y1)

(-19, -13) be (x2,y2)

slope = (y2-y1)/(x2-x1)= (-13+5)/(-19 +18) = 8

Answer: The slope is 8.

Step-by-step explanation: To get the slope you have to do y2 - y1 over x2 - x1. so you take the -5 and subtract -13 from it, which equals 8. Then subtract -19 from -18 which is 1. So you have 8/1 which is 8.

Answers

Answer:

Option C - 0.03 cm

Step-by-step explanation:

The model has a length of 15 cm.

Now, we are told that the scale is 1:500. This means that 1 unit is represents 500 cm on the model.

Since the length on the model is 15 cm which is 15 units, then the true length would be;

15 × 1/500 = 0.03 cm

Therefore, the true length is 0.03 cm.

Option C is correct

Explain why Figure B is not the image of Figure A after a rotation using center P

Answers

Answer:

because the are not the same measurement nor the right placement

Step-by-step explanation:

The sides of figure B appear narrower than the sides of figure A.

We need to explain why Figure B is not the image of Figure A after a rotation using centre P.

What is a rotation?

A rotation is a type of transformation that takes each point in a figure and rotates it a certain number of degrees around a given point.

Now,

The reason why figure B is not the image of figure A after a rotation using centre P includes

1) The angle of rotation is measured as 180 - 45 = 135°, while the angle of rotation of the base is (90 - 26) + (90 - 71) = 83°

2) Rotation of a figure is a rigid transformation, such that the dimensions of the sides of the pre-image and the sides of the image should be equal after the rotation, however, the sides of figure B appear narrower than the sides of figure A.

Therefore, the sides of figure B appear narrower than the sides of figure A.

(2,-9) because it turns 180 degrees meaning your going to rotate it twice.

It should be (2, -9). When rotating 180° you always make the x and y the opposite, so you take the opposite of -2 and the opposite of 9 to get (-2, 9). Hope this helps!

The length of a rectangle is eight more than twice its width. The perimeter is 88 feet. Find the dimensions of the rectangle.

A w = 10 ft, l = 18 ft

B w = 16 ft, l = 28 ft

C w = 18ft, l = 24 ft

D w = 12 ft, l = 32 ft

Answers

Answer:

D w = 12ft, l = 32ft

Explanation:

Make an equation for your length based on the given information.

l = 2w + 8

Make an equation using what you know about the perimeter

p =2l + 2w, p = 88

88 = 2l +2w

Substitute in your previous equation for l.

88 = 2(2w + 8) + 2w

Distribute and simplify.

88 = 4w + 16 + 2w

88 = 6w + 16

72 = 6w

w = 12

Now you can solve for l using the first equation.

l = 2(12) + 8

l = 32

Your answer is w = 12fr, l = 32ft. You can check your work by plugging the values back into the perimeter equation.
