Answer:
I think is 1x+3x=4 and then solve it if you have to
Answer:
Your answer is 4 :)
Step-by-step explanation:
This is because 5 ( the length of the hypotenuse for the small triangle) times 3 equals 15 (the length of the hypotenuse for the bigger triangle). It's only natural that you would find x times 3 equals 12. x(4) times 3 equals 12
therefore 4 is your answer :) I hope I helped, and gosh I love triangle problems like this xD
Do you have any more? If so you can post them and I can do them for you!

Answer:
ly = 14.75
Step-by-step explanation:
4ly – 51 – 8 = 0
4ly - 59 = 0
combine 59 and 0
4ly = 0 + 59
4ly = 59
divide by 4
4ly/4 = 59/4
ly = 14.75
Y = -X + 7
Y = .5(X-3)2
Alright check it out. Substitute the Y in the second equation for the first equation so...
-X + 7 = .5(X-3)2
After this, you have to get rid of the .5 and the 2 which is easy peasy because they just cancel out. If you were to multiply by half and then multiply by 2 then you'd be back to where you started. So...
-X + 7 = X - 3
Move the X to combine them on one side, I moved the -X to the opposite side by adding X to each side so you get...
7 = 2X - 3
You then add 3 to both side so...
10 = 2X
Divide by 2
X = 5
So...
Y = -5 + 7
Y = 2
Y = .5(5-3)2
Cancel out the .5 and the 2
Y = 5-3
Y = 2
(5,2) is your answer
