Answer: In your problem, you said that they are squared. However, it is not written as squared. We just have to multiply them.

We can use the FOIL method.

(3b - 5c)(3x + 5y)

6bx + 15by - 10cx - 25cy

There are no like terms, so that expression is our final answer.

the volume of a rectangular solid, in cubic inches, is given by the expression (x^3-7x+6). if the length and width in inches, ar

nekit [7.7K]

V=x³-7x+6, V=(x-2)(x+3)*h

(x-2)(x+3)*h=x³-7x+6

h{x²+x-6}=x³-7x+6

h=(x³-7x+6)/(x²+x-6)

Therefore h=x-1

-----------------------------

Check answer:

V=(x-2)(x+3)(x-1)

=(x-1)(x²+x-6)

=x(x²+x-6)-1(x²+x-6)

=x³+x²-6x-x²-x+6

=x³-6x-x+6

=x³-7x+6

Answer:

B and D

Step-by-step explanation:

$\frac{2^{5} }{6^{5} } = (\frac{1}{3} )^{5}$

$\frac{2^{5} }{6^{5} } = 2^{5}*6^{-5}$
