Check the picture below. so, that'd be the triangle's sides hmmm so let's use Heron's Area formula for it.

Yes all cubes are similar but their measurement is not similar
Answer:
y=x+5
Step-by-step explanation:
So first you need to plug everything into the point-slope formula which is
y-y1=m(x-x1)
m being the slope and y1 and x1 being the point (5,10)
So once you plug it in it should look like this: y-10=1(x-5)
Now you solve it
First you need to distribute 1 in 1(x-5) which is (x-5)
Now you have y-10=x-5
Then you add 10 to both sides which is y=x+5
Your answer is y=x+5
Answer:
the answer for x is 25
hope this is the answer you are looking for
