Answer:
-9 =x
Step-by-step explanation:
We know these are similar triangles
We can use ratio's to solve
Let CS = y and XR = y+y or 2y
y x+19
------ = ------------
2y x+29
We can simplify the ratio on the left by dividing by y
1 x+19
------ = ------------
2 x+29
Using cross products
1(x+29) = 2(x+19)
Distribute
x+29 = 2x+38
Subtract x from each side
x-x+29 = 2x-x+38
29 = x+38
Subtract 38 from each side
29-38= x+38-38
-9 =x
Well what you want to start off by doing is trying to get the y term by itself.. so well move 2x first
-3y = 6- 2x
then divide by three
y= -2 +2/3 x
Substitute 51/5x into
Substitute that into
Hope this helps. Answer should be correct. Unless your quadratic equation is wrongly stated.
V = a ^ 3
V= 5 ^ 3 = 125 cm cube
