Answer:

l = 14

Step-by-step explanation:

The perimeter of a rectangle is

P =2(l+w)

The width is x-6

w = x-6

The length is 8 units longer than the width

l = w+8

l = x-6+8

l = x+2

We can substitute this into the equation for Perimeter, which is given as 40

40 = 2(x+2 + x-6)

Combine like terms

40 =2 (2x-4)

Divide by 2

40/2 = 2/2 (2x-4)

20 = 2x-4

Add 4 to each side

20+4 =2x-4+4

24 = 2x

Divide by 2

24/2 =2x/2

12=x

We want to know the length

l = x+2

l =12+2

l = 14

Answer:

Shaded area is 55 units²

Step-by-step explanation:

Ignoring the white cutout, we have a rectangle of length 10 and width 7 (count the squares in each direction).  The area of this larger rectangle is

(10 units)(7 units) = 70 units².  The white area that we previously ignored has dimensions 3 by 5 units, and thus an area of 15 units²  

Subtract the latter from the former, obtaining the net area

70 units² - 15 units² = 55 units²

Answer:

17.5

Step-by-step explanation:

(7)*(5)*(.5)= 17.5

Answer:

View attached file!!

Step-by-step explanation:

You need to look at the pattern from the first column and follow the same one through. You could also try to find a linear equation that would help you in this case, although I am not sure if you have learned that yet. Look at the attached image for the answers!

Step-by-step explanation:

You need to follow backwards rule of examples.

Answer:

3 square centimeters.

Step-by-step explanation:

The measurements are 4 cm by 1.5 cm, so you can use the formula for area of a triangle (area = 1/2 * base * height) to figure it out.

Plug in base = 4, height = 1.5:

area = 1/2* 4 * 1.5 = 2 * 1.5 = 3.

The area is 3 sq. cm.

Answer:

No 4 is easy you get 2/3

My explanation is just make the denominator the same which is 13/6 - 9/7

13 x 7/6x7 - 9x6/7x6

The answer it its 91/42 - 63/42

=28/42

If you simply it it would be 2/3

(/ this means by) sorry for my bad explanations

Answer:

A, B, C, E, and F

To solve this problem, you should make sure to find the equation first. Start by doing rise/run with your two given points on the graph. From the point (-1,1) you rise 4 and then run 16 over to the point (3,2). That gives us a slope of 4/16 which can then be simplified to 1/4. That means that letter F tells us the equation of the line is y= 1/4x + 5/4.

From there you want to check your points, (3,2) and (-1,1). The first number is always x and the second number is always y. So you plug the point numbers into the equation we just found to see if they work. In the photos I inserted are how to do this step.

Once you have checked your points and you know for sure they're solutions, that gave you letters A and B. Since the point (1, 3/2) is also given in one of the answers we should check that point as well. (Also done in one of the photos) Since the point came out correctly that gives us letter C and also tells us there is more than 2 solutions. This means that letter E is also correct.

Hope this helped!

Answer:

if I remember correctly it would be a triangle.

Answer:

Step-by-step explanation:

TU , UV , VW, TW are the sides

As points T and U have same x-coordinate, length of TU will be given by the difference of y-coordinate

TU = 9 - 7 = 2 units

As points U and V have same y-coordinate, length of UV will be given by the difference of x-coordinate

UV = 5 - 2 = 3 units

As points V and W have same x-coordinate, length of VW will be given by the difference of y-coordinate

VW = 9 -7 = 2 units

As points W and T have same y-coordinate, length of WT will be given by the difference of x-coordinate

WT = 5 - 2 = 3 units

TU = VW = 2 units

UV = WT = 3 units

So, TUVW is a rectangle

Area = length *width = 3* 2 = 6 square units

Perimeter = 3 + 2 + 3 + 2 = 10 units

Answer:

1. 3x+15

2. 4x+36

3. 4x+36

4. 6x-2

5. 5x-10

6. 4x-24

7. 2x+1

8. 6x+21

9. 4x+16

10. 4x+10

11. x+4

12. 5x-10

To expand an equation, you can apply the distributive property

==> The distributive property, sometimes known as the distributive property of multiplication, tells us how to solve certain algebraic expressions that include both multiplication and addition.

CREDIT: prepscholar.com ^ for the definition of the distributive property

Answer:

Ok so first you want to distribute the -1 in front of the 3x^2-7x+1

Which turns the problem into

X^2+5x-6 -3x^2+7x-1

Then just combine like terms

-2x^2+12x-7

Also ^ followed by the number is the exponent

Answer:

Evidentially, make the photo smaller.

Step-by-step explanation:

It's because dividing 7/8 makes it a smaller number, which will obviously make the photograph smaller.
