I'm assuming that the diagonals intersect at E. Since diagonals of a parallelogram bisect each other, BE=ED.
- 7x-2=x²-10
- x²-7x-8=0
- (x-8)(x+1)=0
- x = -1, 8
As distance must be positive, we reject the negative case, so x=8.
Thus, BE=ED=54.
19
Step-by-step explanation:
when we add 9 and 10 we will get sum 19
Answer:
f(x)=|x-2|+3
0=|x-2|+3
0-3=|x-2|+3-3
-3+2=x-2+2
-1=x
Step-by-step explanation:
- set the function equal to zero
- you can subtract 3 from both sides or you can add -2 and 3 and then you subtract your answer from both sides to solve for x
