The perimeter of a rectangular
cupoosta [38]

Answer:

5 ft

Step-by-step explanation:

Since we have a rectangle, we know for sure that perimeter = double the width and double the height. Algebraically, that looks like:

P = 2W + 2H

Let's sub in the given values, P and W:

18 = 2(4) + 2H

Now, let's solve for the height, H:

18 = 8 + 2H

10 = 2H

10/2 = H

<u>5 = H</u>

I hope this helps!

HELP ASAP PLEASE!!!
xenn [34]

Answer:

E. None of these

Step-by-step explanation:

Points: (11, -4), (13, -7)

slope = m = (y2 - y1)/(x2 - x1) = (-7 - (-4))/(13 - 11) = (-7 + 4)/2 = -3/2

y - y1 = m(x - x1)

y - (-4) = (-3/2)(x - 11)

y + 4 = (-3/2)x + 33/2

y + 8/2 = (-3/2)x + 33/2

y = (-3/2)x + 25/2

Answer: E. None of these

CAN SOMEONE PLEASE HELP ME ASAP PLEASEEEE!!!​
Rom4ik [11]

Answer:

11.4

Step-by-step explanation:

So we know that Triangle ACB is similar to Triangle EFD.

This means that their sides are proportional to each other.

We want to find x or side AB. To do so, we can set up a proportion.

The proportional side to AB is ED. Let's also use BC since we know its value. The proportional side to BC is DF. Thus:

\frac{AB}{ED}=\frac{BC}{DF}

Substitute x for AB, 3.8 for Ed, 15 for BC, and 5 for DF. Thus:

\frac{x}{3.8}=\frac{15}{5}

Reduce the right:

\frac{x}{3.8}=\frac{3}{1}

Cross multiply:

x=11.4

So, the value of x is 11.4

And we're done!
