Answer:
like terms are numbers or letters that are a like.
y² is the only letter with a square in this problem. Whilst xy and 2xy are the same.
y²+ xy + 2xy
y² there is no letter with square again.
xy+2xy is the same as one orange + two orange.
1 is never written against a letter.
y²+ xy + 2xy
y²+3xy
Answer:
16896
Step-by-step explanation:
3×1×11×512
=16896
So they're proportional.
This means that the 2 triangles are exactly the same BUT the right one is smaller than the other, so all measurements are smaller too.
So to find the distance, you need to find the scale factor.
Think of it like this: 82m becomes 73.8m, and 92m becomes 82.8m.
Find the scale factor by finding the ratio.
73.8/82 = 9/10 or 0.9
You could do the same thing with the other two numbers too (92/82.8), gives the same answer.
Times the ratio by the distance of the bigger triangle:
0.9 x 47 = 42.3m
Answer:
2x^2-6x-4
Step-by-step explanation:
(7x2 + 4x - 9)
-(5x2 + 10x - 5)
=
7x^2-5x^2=2x^2
4x-10x=-6x
-9-(-5)=-4
thus, your answer is 2x^2-6x-4
