Readme [11.4K]

Answer:

<h2>V = 70x⁹ cubic units</h2>

Step-by-step explanation:

The formula of a volume of a rectangular prism:

V=lwh

l - length

w - width

h - height

We have:

l=7x^3,\ w=5x^2,\ h=2x^4

Substitute:

V=(7x^3)(5x^2)(2x^4)=(7\cdot5\cdot2)(x^3x^2x^4)=70x^{3+2+4}=70x^9

Used

a^n\cdot a^m=a^{n+m}

Can someone PLEASE solve this quadratic equation by factoring with the steps? :(
salantis [7]

Answer:

There are no simple factors to this expression.  You can however solve for x, giving you:

x = -1 ± √(y + 3)

Step-by-step explanation:

There is no simple pair of factors to this equation, so we'll have to go through the full process.  You can see that by observing that there is no pair of rational numbers that add to make 2 and multiply to make -2.  We can however solve for x:

y = x^2 + 2x - 2\\y + 2 = x^2 + 2x\\y + 3 = x^2 + 2x + 1\\y + 3 = (x + 1)^2\\(x + 1)^2 = y + 3\\x + 1 = \pm \sqrt{y + 3}\\x = -1 \pm \sqrt{y + 3}
