Which shows 232 − 172 being evaluated using the difference of perfect squares method?232 − 172 = (529 + 289)(529 − 289) = 196,320
232 − 172 = 529 − 289 = 240
232 − 172 = (23 + 17)(23 − 17) = (40)(6) = 240
232 − 172 = (23 − 17)2 = (6)2 = 36

Answers

Answer 1
Answer: difference of perfect squares is a² - b² = (a+b)(a-b)

Here, we can let 23 = a and 17 = b, so using this method, we have
23² - 17² = (23+17)(23-17) = 40 × 6 = 240

So third option is correct.
Answer 2
Answer:

Answer:

Your answer is 23^2 − 17^2 = (23 + 17)(23 − 17) = (40)(6) = 240, or C on your answer sheet.

Step-by-step explanation:

Lets begin!

So when a binomial is composed of two perfect squares separated by a subtraction symbol, a certain method called the difference of perfect squares can be used. The difference of perfect squares method can be done by multiplying the sum and difference of the two square roots.

So, to solve:

23^2 - 17^2 = (23 + 17)(23-17) = (40)(6) = 240

Thus being your answer.

The equatorial diameter of a model of earth is 25.6 cm. What is the total surface area of the model​

Answers

Answer:

2059.7\,\,cm^2

Step-by-step explanation:

Diameter of a model of earth (D) = 25.6 cm

Radius of a model of earth (r) = (D)/(2)=(25.6)/(2)=12.8\,\,cm

Earth has the shape of a sphere.

Total surface area of a sphere = 4\pi r^2

Put \pi=(22)/(7)\,,\,r=12.8\,\,cm

So,

Total surface area of the model =4((22)/(7))(12.8)^2=2059.7\,\,cm^2

What are the coordinates of the image produced by applying the composition Ro,-270 degrees o Ro,-90 degrees to the point (–5, 4)?A. (–5, 4)
B. (–4, –5)
C. (4, 5)
D. (5, –4)

Answers

On dealing with a rotation of -270 degrees or 90 degrees (both are equal to each other), it is necessary to know the relation between the x and y coordinates to know the new coordinate points of the rotated image. The rotation relation for a 90 degree rotation is:

R90 (x,y) = (-y , x)

Therefore, with that being applied to the point (-5,4), the new coordinate points of the rotated image would be: (-4,-5). Among the choices, the correct answer is B.

How does the speed change on the Graph? And what does a steeper line mean?

Answers

The steeper the line is (the larger the slope), the faster the speed is.  This is due to the fact that speed=distance/time and the slope=y/x which is distance over time on a distance v time graph.

X + x - 5 greater than equal to 33

Answers

To write this inequality first lets write the word form. The determine the symbol, and write it out:-

x + x - 5 greater than or equal to 33

greater than or equal to sign is ≥.

lets write it out with the sign:-

x + x - 5 greater than or equal to 33.
x + x - 5 ≥ 33

If we were to write this in correct words it would be 

A number plus a number minus five, is greater than or equal to thirty-three. 

Hope I helped ya!! xD
