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

(X+5)+(x-5)=56 what does x=?
kirill115 [55]

Answer:

x=28

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

x+5+x−5=56

x+5+x+−5=56

(x+x)+(5+−5)=56(Combine Like Terms)

2x=56

2x=56

Step 2: Divide both sides by 2.

2x/2=56/2

x=28

Find the slope (m) of the line containing the points (1, 2) and (2, 5).
Vladimir [108]

Answer:

<h2>3</h2>

Step-by-step explanation:

<h3>Step 1: Identify two points on the line</h3>

1,2 & 2,5

<h3>Step 2: Select x1, y1 & x2, y2</h3>

x1 = 2, y1 = 5     x2 = 1, y2 = 2

<h3>Step 3: Use the Slope Formula</h3>

change y/ change x

<u><em>IMPORTANT: it is change in y over change in x, not the other way around. It will be wrong if done the other way, though that would seem to be more logical, since x is the first variable in the pair.</em></u>

Y   5 -2 = 3        

X   2 - 1 = 1

3/1 = 3
