(2m-7)(2m-7)
4m^2 - 14m - 14m + 49
4m^2 - 28m + 49

Answer: 4m²-28m+49

Step-by-step explanation:

(2m-7)² can be written as (2m-7)(2m-7).

You would have to multiply it out like this:

2m times 2m=4m² (2x2=4 and mxm=m²)

2m times -7=-14m (2x-7=-14 then put a m on it)

-7 times 2m=-14m

-7 times -7=49

The equation would then look like this:

4m²-14m-14m+49

Then you would have to collect like terms. Like terms are terms with the same variables and powers. It will then look like this:

4m²-28m+49

Hope this helps :)

C,E, and F are your answers. There are 10 rows in each box and 2 are full the other has 8 filled

Letter C, E, and F: 2 8/10, 2.8, and 28/10

Step-by-step explanation: The shaded pillars/rectangles inside the squares account for the fractions. In this question, there are 10 pillars per square and 2 shaded in squares. Since there are two full squares, there are two wholes. In the third block, there are only 8 shaded. Because 8 out of ten are shaded, the fraction would be 8/10 (said as eight tenths). Overall, there are two wholes (the shaded squares) and 8/10 of a whole. Therefore, it is 2 8/10. 0.8 equals 8/10 (you can determine it by the way it is said ex: you would say “zero and ...” (and = decimal) “... eight tenths” or just “eight tenths” for .8, and 8/10 is said the same way). Since 2.8 and 2 8/10 are equal, 2.8 would also be an answer. 28/10 would be another correct answer because the two wholes/squares each have 10 pillars. In total, there are 20 pillars for the two wholes. If the 8/10 (8 out of 10) is added, the total would be 28/10. Hope this helps!

So the scaling means that per every foot in real life, you have 2.4 centimeters, which means that the scale model would be 48 cm tall.

A. To find your answer, you would divide 48 by 1.2, which is 40. So your model would be 40 bottle caps tall

B. Same as A, all you have to do is divide 48 by 15.2, which would be about 3 popsicle sticks tall (rounded)

In the diagram, line GH is perpendicular to line IJ. What is the measure of angle 1?


A. 37°
B. 53°
C. 63°
D. 74°

Answers

Answer: B

Explanation: 37+53= 90 and it being perpendicular creates a right angle of 90 degrees
Answer is 53 because these are supplementary angles and they adapt to 180 degrees. You add 37 and 90= 127, and then you subtract 127 from 180.

To pass her test, Tori needs to answer at least 65% of the questions correct. If there were 60
questions and she got 42 correct, did she pass? All work MUST be shown to justify your
answer.

Answers

1) change 65% to a decimal = .65

2) .65 • 60 = 37.2 questions need to be right

3) since she got 42 correct, that is greater than 37.2, so she passed.

OR

1) 42/60 = 0.7

2) 0.7 to a percent = 70%

3) since she got a 70% on the test, she passed.

Step-by-step explanation:

To obtain score of 80% on entire exam means the student have to answer

(80/100)×80 = 64 correct answers

Student have already answered 75% of the first 60 questions correctly meaning

(75/100)×60=45 correct answers from first 60 questions

Remaining correct answers s/he have to answer

64-45=19

So from remaining 20 questions s/he have to answer 19 correct questions that is

20 × (x/100) = 19

x = 19 ×(100/20)

x = 95%
