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.
Answer:
90 degrees since its vertical angle
Answer:
130
Step-by-step explanation:
The Honda will cost 24480 - 1400 = 23080
The Toyota will cost 25500 - 0.1 * 25500 = 25500 - 2550 = 22950.
So the Toyota will cost 130 less
54 divided by 6 would be 9 meaning he takes 9 quizzes a week. If directly proportional by the end of 7 weeks he would have taken 63 quizzes
600+30+7 if that is what you meant...
