Answer:
84 x^12
Step-by-step explanation:
(4x)(-3x^8)(-7x^3)
Multiply the numbers
4*-3 *-7 = 84
x* x^8 * x^3 = Add the exponents = x^(1+8+3) = x^12
84 x^12
Since none of the options make sense with 23, I assume it was a typo, and you meant 2/3.
Let l,w and h be the length, width and height of the original prism, and l',w' and h' be the length, width and height of the new prism. We are given

Also, if we call V the original volume, and V' the volume of the new prism, we have

Substitute the expressions for l', h' and w' in the formula for V':

7+x^3. It cannot be simplified further without knowing the value of x
Answer:
Step-by-step explanation:
distance PQ=√[(0-0)²+(2+11)²]=√13²=13
distance AB=√[(-3-0)²+(-4-0)²]=√(9+16)=√25=√5
distance CD=√[(0-8)²+(-6-0)²]=√(64+36)=√100=10
