Answer:
-2
Step-by-step explanation:
I prefer D.
It's clear that Kevin took (1/4)x.
Keith took (1/4)x -> kevin's amount
* 2 -> twice.
-1 -> 1 less.
So Kevin + Keith = (1/4)x + (1/4)x * 2 - 1 = (3/4)x - 1.
It’s X= 14 I did that one before and I got it
Answer:
B
Step-by-step explanation:
The interior of the 4 triangles in the rhombus are right angle triangles. In addition AC is bisected by BD and BD is bisected by AC. Those form the sides of the right angle triangle.
So the sides of the right angle are
- 1/2 17 = 8.5 and
- 1/2 15 = 7.5
The area of one right angle is
- 1/2 * 8.5 * 7.5 = 1/2 * 63.75 = 31.875
- But there are 4 of them
- Area of the rhombus = 4 * 31.875 = 127.5
The answer is B
