hey so sorry to bother you but i have a test that was due last week and i need help on a couple of the problems if thats alright

x = 3

Step-by-step explanation:

These 2 triangles are proportional, meaning corresponding sides are proportional to each other.

We can figure out how to find x by doing this:

48 ÷ 8 = 6. Now we know that the left triangle is 6 times larger than the right, or that the right triangle is 6 times smaller than the left. They mean the same thing.

18 ÷ 6 = 3. When we divide the side corresponding with x by 6, we are now solving for x.

Your final answer is x = 3.

Note how 3 is 6 times smaller than the corresponding side on the left triangle.

Hopefully this helps you understand this a bit better :)

the infinity sign

step-by-step explanation:

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
