If a quadrilateral is a parallelogram, it has diagonals which form 2 congruent triangles. Use the following, to PROVE a parallelogram: DEFINITION: A parallelogram is a quadrilateral with both pairs of opposite sides parallel.
That’s what I got I didn’t know how to type it so I just took a photo
So 30/48=15/(x+9)
this could be easily solved by recognizing the proportion (the other way is usiing full algebra and doing multiply both sides by 48(x+9) and then divide both sides by 30 then subtract 9)
30 is 2 times of 15
therefor 48 is 2 times of (x+9)
48=2 times (x+9)
divide both sides by 2
24=x+9
subtract 9
15=x
x=15
Answer:
2x + 3t - 4
Step-by-step explanation:
Hi,
To simplify the expression, we must combine like terms. To start, let's combine all of the x-values.
4x + 3t - 2x - 4
When we combine 4x and -2x we get 2x.
2x + 3t - 4
We can't combine anything else. They don't have the same variables and 4 doesn't even have a variable, so 2x + 3t -4 is the simplified expression.
I hope this helps :)
