What is the combined perimeter of these two rectangles?
GarryVolchara [31]

Answer:

D) 24x + 52

Step-by-step explanation:

The perimeter of the purple rectangle is

P =2(l+w)

   =2 (4x+5  + 2x+7)

Combine like terms

   =2 (6x+12)

Distribute

  = 12x +24

The perimeter of the white rectangle is

P =2(l+w)

P =2(3x+14 +3x)

Combine like terms

  =2(6x+14)

Distribute

 12x +28

Add the perimeters

12x +24 +  12x +28

24x +52

Given that k(x) = (2x + 4)2
taurus [48]

Answer:

f(x)=4x\\g(x)=x+2

Step-by-step explanation:

Because we have to rewrite this equation in the format f(g(x)), we have to divide, or factor to find basic terms,

Expanding the value of k(x), we have k(x)=4x+8. We see that each term can be divisible by 4, so we can factor out 4 to get

k(x)=4(x+2)

Now, we have two different terms getting multiplied. We can separate the two to get 4 \text{ and} (x+2)

Because we are multiplying 4 by the other term, this is represented by 4x

Now, we can just set f(x) and g(x) to these functions:

f(x)=4x\\g(x)=x+2

Now, just to make sure, we can plug a value into k(x) and the same value into f(g(x)). Plugging in 1, we have (2(1)+4)2 as 2(2+4), which is 2(6) = 12.

Plugging 1 into f(g(x)), we can evaluate g(1) first, to get 1 + 2 = 3. Now, f(3) = 4(3)= 12, which is the same for k(x).

Find the total surface area of the net below.
Solnce55 [7]

Total surface area of the triangular prism is  81.6 square m.

Step-by-step explanation:

  • b = 3 m
  • h = 2.6 m
  • p = 3+ 2.6 +2.6=  8.2
  • H = 9 m
  • SA = bh + pH

    = 3 × 2.6 + 8.2 ×9

    = 7.8 + 73.8

    = 81.6

  • Therefore,
  • SA = 81.6 square m
  • Total surface area of the triangular prism is  81.6 square m.

On a science test, 2 points are deducted from a total of 100 points for each question answered incorrectly. Trevor scored an 84
CaHeK987 [17]

Answer:

8

Step-by-step explanation:

Using the equation in the directions (100-2x=84), we can find out how many questions Trevor got wrong on his Science test. First, we need to subtract 100-84=16 to find out how many points he lost. Trevor lost 16 points.  Now we can divide 16/2=8, to find out how many questions he got wrong. Trevor got 8 questions wrong on his test.

Hope this helps!
