Answer:
Step-by-step explanation:
5(x-3y)+2(4x+y)-(x+y)
5x-15y+8x+2y-x-y
5x+8x-x-15y+2y-y
13x-x-13y-y
12x-12y
Answer:
x = 5
Step-by-step explanation:
x is the length of the hypotenuse of this triangle. The length of one of the legs of the triangle is 3" and that of the other leg is 4".
Applying the Pythagorean Theorem: x^2 = 3^2 + 4^2, or 25
Thus, the length x is +√25, or 5.
x = 5
