You are going to want to isolate the variable shave u done tht yet
Answer:
108
Step-by-step explanation:
cross multiply fractions:
12/72 = 18/x
x = 108
Step-by-step explanation:
1: Solve one Equation for one of the variables
2: Substitute (plug-in) this expression into the other equation and solve
3: Resubtitue the value into the original equation to find the corresponding variable
Recall that to calculate the distance between two points (a,b) and (c,d) we use the formula
![\sqrt[]{(c-a)^2+(d-b)^2}](https://tex.z-dn.net/?f=%5Csqrt%5B%5D%7B%28c-a%29%5E2%2B%28d-b%29%5E2%7D)
In our case we have a=-2, b=5, c=4 and d=5. So we get
![\sqrt[]{(4-(-2))^2+(5-5)^2}=\sqrt[]{6^2}=6](https://tex.z-dn.net/?f=%5Csqrt%5B%5D%7B%284-%28-2%29%29%5E2%2B%285-5%29%5E2%7D%3D%5Csqrt%5B%5D%7B6%5E2%7D%3D6)
So the distance between both points is 6
2x^2+3x-54 that’s the answer .
