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

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!

Answer:

The number covered by the car is 87.

Step-by-step explanation:

All you have to do is turn the picture upside down, revealing a bunch of numbers in a row.

Answer:

87 but since its upside down L8

Step-by-step explanation:

The answer is L8. All of the numbers, when read upside down, are the number 86 - 91

So basically 87 but upside down it would be L8.

Answer:

Answer: A 5

Step-by-step explanation:

20% * 25

= 0.2 * 25

= 5

She can expect to hit the bullseye 5 times.

Answer:

A. 5

Step-by-step explanation:

Regina throws 25 darts and hits the bullseye 20% of the time. So we would set up the equation as 0.20*25 (as we are looking for 20% of 25 and of means multiplication and 20% is 0.20). 0.20*5=5 so she can expect to hit the bullseye 5 times. Therefore, A is the correct answer choice.

Answer:

check below

Step-by-step explanation:

1.  c = 68-27 = 41

2. t = 7.9+1.5 =9.4

3. a = 21*3 = 63

4. (multiply whole equation by 8) 8r+6=7, r=1/8

5. x = 25.2/4.2 = 6

6. b = 75/15 = 5

7. A. 6C = 99

B. C = 99/6 = $16.50

The solution represents the cost of one ticket.

Answer:

Step-by-step explanation:

Basically, try finding the x and y intercept for each problem and then make those your coordinates!!

Step-by-step explanation:

1) So to answer these questions first plot the "b" value (which in number 1's case would be 3).

2) Go up three spaces on the graph. and that should leave you at the point (0,3) Plot this point.

3) Now go down 3 (-3x) and go over one point to the right(this should put you at point (1,1). Plot this point.

4) Move on to the next equation in number one. Go up three spaces on the graph.

5) Go down one and over one until you find that you have plotted a point in which both equations intercept (this point would be (0,3).

6)Repeat this process for the rest of the problems

Answer:

A) 25%

B) 6.5%

Step-by-step explanation:

A) 10/39.99≈0.2501

    25%

B) 1.95/29.99≈0.0650

    6.5%

Answer:

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)

(Hope this helps)

Step-by-step explanation:

a) a+b=b+a

the commutative property of whatever number is it turned around

b) a * b= b*a

the commutative property of whatever number is it turned around

c) b+0=b

the additive property is whatever adds to zero is that number.

d) b*1=b

the multiplication property of one is whatever mutilply by 1 is that number.

Answer:

Tiffany just got an aquarium for her rare turtle. She wants to fill it with water but it came without the volume measurement on it. She measures and finds aquarium's length is 30 inches, width is 12 inches, and height is 18 inches. How many cubic inches of water does she need?

Step-by-step explanation:

The formula for right rectangular prism is Length×Width×Height

30×12×18 = 6480

So she needs 6,480 in³ of water

Answer:

41% & 45%

Step-by-step explanation:

A fraction consists of two numbers and a fraction bar:

41/45

The number above the bar is the numerator: 41

The number below the bar is the denominator: 45

Divide the numerator by the denominator to get fraction's value:

Val = 41 ÷ 45
