Answer: First option 13
Solution
If ABCD is a rhombus, the diagonals must be perpendicular, then the angle (5x+25)° must be a right angle (90°):
(5x+25)°=90°
5x+25=90
Solving for x: Subtracting 25 both sides of the equation:
5x+25-25=90-25
Subtracting:
5x=65
Dividing both sides of the equation by 5:
5x/5=65/5
Dividing:
x=13
Answer: The value of x must be 13
Answer:
8x^2+4x-24
Step-by-step explanation:
A=LW
(4x-6)(2x+4)
8x^2-12x+16x-24
8x^2+4x-24
Answer: 1400 students
Explanation:
Total = 4000
Senior = 1/8 x 4000 = 500
Senior not in favor of debate = ( 1 - 1/5) x 500 = 400
Non senior = 4000 - 500 = 3500
Non-senior not in favor of debate = (1 - 5/7) x 3500 = 1000
Total = 400 + 1000 = 1400
It looks like only A and B, but could be trick question?
OK. Even though you only gave me part of the paragraph, I read that much, and I think I'm ready to select the correct answer now. What are the choices ?
