sum is angles of a Pentagon=540°

x°+138°+2x°+80°+112°=540°

3x°+330°=540°

3x°=540°-330°

3x°=210°

The area of the large rectangle is twice the area of the small rectangle. What is the value of x?Two rectangles are shown. The l
kupik [55]

Answer:

B. 8 cm.

Step-by-step explanation:

The area of a rectangle is the length*width.

The area of the larger rectangle is 4*12=48.

The area of the smaller rectangle is 3*x=3x.

If the larger rectangle's area is twice that of the smaller rectangle, then we can say 48=2*3x.

Let's solve for x

48=2*3x

48=6x

x=8

Hannah was asked to make d the subject of the formula<br> d-7=4d+3/e<br> Finish her question.
tigry1 [53]

Answer:

d = \frac{-1}{e} - \frac{7}{3}

Step-by-step explanation:

In order to make d the subject of the formula, you need to isolate it.

- You started with d-7 = 4d + 3/e

- Move 4d to the left side by subtracting 4d from both sides to cancel it from the right so you have...

d - 7 = 4d + 3/e              This will leave you left with -3d - 7 = 3/e

-4d     -4d                          

- Then move over the -7 by adding 7 to both sides...

-3d - 7 = 3/e              This will leave you left with -3d = 3/e + 7

     +7          +7

- Finally to get d by itself divide both sides of the equation by -3 and you'll be left with...

d = \frac{3}{-3e} -\frac{7}{3}

- You can cancel out the 3 in the -3/3e and make it -1/e so your final answer will be

d = \frac{-1}{e} - \frac{7}{3}
