Answer:

perimeter- 36 in.

area- 77 $in^2$

Step-by-step explanation:

to find the perimeter you add all of the sides, so

7 + 7 + 11 + 11 = 36

*** the opposite side of the 7 is also 7, same with the 11 :)

to find the area for a rectangle, you use the formula A=b*h

so, the base(b)=7 and the height(h)= 11

therefore, 7 * 11 = 77

I hope this helps!! :) if it does, brainliest?? :)

If A = {2, 3, 4, 5} and B = {5, 6, 7, 8}, what is A U B? {2, 3, 4, 5, 6, 7, 8) {5}

Ulleksa [173]

Hey!!!!

Here's your answer:

Solution:

A={2,3,4,5}

B={5,6,7,8}

 A U B={2,3,4,5} U {5,6,7,8}

 ={2,3,4,5,6,7,8}

In case of Union,we have to list all the elements which are present in both sets.

Hope it helps...

Good luck on your assignment

Find x. I had been stuck on this one for awhile

Arlecino [84]

Answer:

34 degrees

Step-by-step explanation:

ok so 180-111=69

then the opposite angle from 37 is also 37

the the missing angle from the left triangle has to be 103

so then the angle below x is 77

and so we know x = 34 degrees

I hope that made sense.

How do you slove 3x+4y=8 in steps

gavmur [86]

3x+4y=8
Add -4y to both sides
3x+4y+−4y=8+−4y3x=−4y+8
Then you divide both sides by 3
3x/3=−4y+8/3x=−4/3y+8/3
And your answer is ...
x=−4/3y+8/3
