Answer:
216 cm³
Step-by-step explanation:
large prism volume = 6 x 6 x 8 = 288 cm³
small cutout volume = 3 x 3 x 8 = 72 cm³
288- 72 = 216 cm³
Answer:
12
Step-by-step explanation:
let x be the broken ht. then hypotenuse will be 18-x.
sin 30 = x/(18-x)
1/2 = x/(18-x)
18-x = 2x
3x = 18
x = 6
18-6 is the ht of broken part which is 12
Answer:
If,

But 3^x ≠ 21875,if x is a whole number.

Answer:
The answer is the last option, D.
Step-by-step explanation:
A function with one solution can be added and have a variable and a constant leftover. The variables in the other three options cancel each other out, so none of them have one solution. The first and third equations have no solutions, and the second has infinitely many solutions. The fourth option has only one variable cancel out and still has a constant on the other side of the equation. The fourth option is correct.
