I got the last answer on the screen.
Answer:
Step-by-step explanation:
12 - 12x = -6x + 48
Add 12x to both sides. That eliminates the x term on the left side.
12 = 6x + 48
Subtract 48 from both sides. That eliminates the constant term on the right side.
-36 = 6x
x = -6
2/15+3/15=5/15 5 can go into both 5/5=1 and 15/5=3 which means
=1/3 is the answer
Answer:
6 and -14
Step-by-step explanation:
Area of the triangle = 1/2 ab
42 = 1/2 (x)(x+8)
42 *2 = x(x+8)
84 = x²+8x
x²+8x-84 = 0
x²+14x-6x-84 = 0
x(x+14)-6(x+14) = 0
x-6 = 0 and x+14 = 0
x = 6 and -14
Hence the values of x are 6 and -14
