2x. Use variables. "X" is our variable. Bob has x brothers. If john has 2 times as many you multiply so it would equal 2x

Let, J = John and B = Bob

2J = B

Because you didn't give me a number we are making an expression

2J = b

Make J = 1

J = b/2

George and his dad made some snack mix for their camping trip. To make it, they used 2 cups of mini pretzels, 3/4 cup of peanuts

Tamiku [17]

They had 17/12 ( 17 over 12, or 1 and 5 over 12)
So the fractions have to have the same denominator. 12 is their common denominator. So:
3/4 = 9/12
2/3=8/12

8/12+9/12= 17/12 or 1 and 5/12

How do you solve for x in x^2+5x=36

Vlad [161]

First we want to set the equation equal to zero by subtracting 36 from each side...

x^2 + 5x -36 = 0

Now we factor

(x + 9)(x - 4) = 0

Now set each expression equal to zero and solve...

x + 9 = 0 x - 4 = 0
x = -9 x = 4

Your solution set is

(-9, 4)

What is the polynomial function of lowest degree with leading coefficient of 1 and roots mc024-1.jpg, –4, and 4? (image is √3)

Nookie1986 [14]

$\bf \begin{cases}
x=\sqrt{3}\implies &x-\sqrt{3}=0\\
x=-4\implies &x+4=0\\
x=4\implies &x-4=0
\end{cases}
\\\\\\
(x-\sqrt{3})(x+4)(x-4)=\stackrel{y}{0}\implies (x-\sqrt{3})(\stackrel{\stackrel{difference}{of~squares}}{x^2-4^2})=y
\\\\\\
(x-\sqrt{3})(x^2-16)=y\implies x^3-16x-x^2\sqrt{3}+16\sqrt{3}=y
\\\\\\
x^3-x^2\sqrt{3}-16x+16\sqrt{3}=y$
