Answer:
all the possible values of y - x are 4 and 5
all possible values of x/y = 1
Volume=lengthXwidthXheight
far left— 8x8x20= 1280ft^3
middle— 60-8=52-20=32 so you find out the length of just that piece of solid
20-12=8 to find out width
8x8x32=2048ft^3
far right— 20x15x8=2400ft^3
volume of whole shape- add each value together 1280+2048+2400=5728ft^3
volume= measurement^3
Answer:
17
Step-by-step explanation:
2x - y = -2 . . . (1)
5x - 2y = -7 . . . (2)
From (1), y = 2x + 2 . . . (3)
Putting (3) into (2), gives:
5x - 2(2x + 2) = -7
5x - 4x - 4 = -7
x - 4 = -7
x = -7 + 4 = -3
y = 2(-3) + 2 = -6 + 2 = -4.
Therefore, the required answer is (-3, -4)
Answer: B, C, D
Step-by-step explanation:
- A <u>rectangle</u> must have at least one right angle, not a rhombus. So, A is wrong.
- This is a specific property of a rhombus, so B is correct.
- This is a specific property of a rhombus, so C is correct.
- Since all rhombi are parallelograms, and diagonals of a parallelogram bisect each other, D is also correct.
