Answer:
x=10
Step-by-step explanation:
10-7=3
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
Answer:
For first equation:
x = 18.5
For second equation:
x = 4.25
Step-by-step explanation:
First one:
-2x + 54 = 17. Subtract 54 on both sides.
-2x = -37. Divide all by -2.
x = 18.5
Second one:
4x - 54 = -9. Add 54 to both sides.
4x = 45. Divide all by 4.
X = 4.25.
The answer is 900 because if you add up all the sides of 225 you will get that answer for that
