Answer:
x = 7
Step-by-step explanation:
A rhombus is a parallelogram where all sides are equal. Therefore, as we know two sides are equal to 7x+8 and 9x-6, we can say that
7x+8 = 9x - 6
subtract 7x from both sides to put the variable on one side
2x - 6 = 8
add 6 to both sides to isolate the variable and its coefficient
2x = 14
divide both sides by 2 to isolate x
x = 7
y=5x-3
y=5×5-3
y=25-3
y=22
i am not posotive about the answer but i think it is right
4/3 * pi * 8^3 (8 cubed)
= 2144.6605....
= 2145mm^3
