Question

Find the missing side length.
Assume that all intersecting sides meet at right angles.
Be sure to include the correct unit in your answer.

Answer 1

Is there a screenshot/image at all?

Answer 2

If you can hold on for just a little, that'd be great. :)

Answer 3

ok ty for helping me!

Answer 4

All the measurements;

8cm 12cm 9cm 16cm 7cm

Measurements you need;

8cm 12cm

What do you do with 12 and 8 to get "?"?

Subtract, add, multiply, divide?

Answer 5

Solving this is quite easy. Looking at the missing side, we can see that our x side, or unknown plus 8 cm equals the opposite side, which is 12. Giving us an equation of:

x + 8 = 12

We just have to solve for x

Answer 6

As you can see in the picture, the top side is exactly the same as the bottom side, with an extra box on it. Since the bottom is equal to the top, we can set up the equation:

8 + x = 12

Answer 7

oh ok so I add right.

No. You do not add 12 and 8. What is the opposite of adding?

Answer 9

subtracting

Good job! You got it. :)

x = 4

Answer 13

ohhh i get it now so we do the opposite like, sub, add, divi, and multi.

Anytime!

Answer 17

Essentially to solve a function like:

x + 8 = 12

We have to isolate the value of x. Now how would we get x alone on one side of the equation? We would subtract 8 to get it off the right side, that way x is alone. That's how we solve a function. Just isolate the x, or unknown value.
