Answer:

-6m-n+3

Step-by-step explanation:

Answer:

I think I got it but dont think it's right but -6m-n+3

Step-by-step explanation:

So -3(2m-1) if you multiply-3 by 1 it will equal -3 so if you multiply it by 2 that equals -6 so then you have -6m-n-3 but If you dont thinks it's right dont awnser with my awnser

Answer:

90sqft

Step-by-step explanation:

We have the base and the height, so we just compute

A = bh/2

A = 12ft * 15ft / 2 = 180sqft / 2 = 90sqft

Answer:

2x+21

Step-by-step explanation:

Area=Base*height

(x+7)*(x+3)

x*x=2x

7*3=21

2x+21

Answer:

Area=Base*height

(x+7)*(x+3)

x*x=2x

7*3=21

2x+21

Answer:

(-3, -7)

Step-by-step explanation:

y = 4x + 5

y = x - 4

add 4 to both sides of the second equation to get y + 4 = x

plug that back into the equation to get y = 4(y + 4) +5

distribute to get y = 4y + 16 + 5

combine like terms y = 4y + 21

subtract 4y on both sides to get -3y = 21

divide both sides by -3 to get y = -7

plug -7 into the second equation to get -7 = x - 4

add 4 on both sides to get -3 = x

therefore (-3, -7)

Answer:

i think you are mistaken. it would have to be "what two numbers when multiplied equal -12 and when added equal 4"

if that's the case then the answer would be -2 and 6

Step-by-step explanation:

-2*6=-12

-2+4=4

Answer:

its not possible because if we say 2: 2 + 2 is 4 and 2 x 6 is 12 it would have to be two numbers that both add up to 4 and multiply to 12

Step-by-step explanation:

2 + 2 = 4

2 x 6 = 12

Answer:

It took each girl 1/8 hour to print their project.

Step-by-step explanation:

1/2 hour = 30 minutes

30 minutes / 4 girls = 7.5 minutes for each girl to print their project

7.5 minutes / 60 minutes in an hour = 0.125 or 1/8 hour

Hope this helps!

Answer:

The answer is C, b>=16

Explanation:

Answer:

62.5

Step-by-step explanation:

Finally, we need to subtract the area of the triangle from the area of the rectangle to find the area of the banner: Area of banner = Area of rectangle - Area of triangle Area of banner = 70 - 7.5 Area of banner = 62.5 square inches So, the area of the banner is 62.5 square inches.

Answer: its 34.5

Step-by-step explanation:

Answer:

it is not a right triangle because 130 does not =121

Answer:

b)in order to do that you have to write out your problem using a proportional relationship. you start with picking out your scale factor and then you use that to calculate your enlargement. lets say your scale factor is 3:1.

3/1=x/21 x=63

c) 5/1=x/21 x=105       the appx. area of the park in the enlarged drawing will be 105ft sq

d)I identified the scale factor in each problem and then applied it to each of the separate situations in order to enlarge or reduce an amount/ image.

Step-by-step explanation:

The approximate area of the park of the park in your enlarged drawing is given by A = 105 inches²

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the proportion be represented as A

Now , the value of A is

The area of the map = 21 inches²

And , the scale factor of proportion is 5 : 1

So , the area of the drawing is given by

A / 21 = 5 / 1

Multiply by 21 on both sides , we get

A = 105 inches²

Therefore , the value of A is 105 inches²

Hence , the area of the drawing is 105 inches²
