The sum of three consecutive odd numbers is 159.<br> What is the smallest of the three numbers ?
natta225 [31]

Since we don't know where to start, we can always give that a variable which in this case, it's X. Since we are finding the sum of three consecutive odd numbers, we will be skipping numbers so we can add 2 each time. Now, let's set up an equation.

<h2>X + X + 2 + X + 4 = 159</h2><h2 /><h2>3x + 6 = 159</h2><h2>       -6     -6   ← subtract 6 on both sides</h2><h2 /><h2>       3x = 153</h2><h2>       ÷3     ÷3   ← divide both sides by 3</h2><h2 /><h2>          X = 51</h2><h2>          X + 2 = 53</h2><h2>          X + 4 = 55</h2><h2 />

Therefore, the smallest of our three consecutive integers is 51.

Find the zeros of each function by using a graph and a table. f(x)=x^2+2x–24.
Alborosie

Explanation

Step 1

f(x)=x^2+2x-24

Zeros

A(-6,0) B(4,0)

because

\begin{gathered} f(x)=x^2+2x-24 \\ f(-6)=(-6)^2+2(-6)-24=36-12-24=0 \\ f(4)=4^2+2\cdot4-24=16+8-24=0 \end{gathered}

Step 2

table

\begin{gathered} (-6,0) \\ (4,0) \\ f(-1)=-1^2+2\cdot-1-24=1-2-24=-25 \\ (1,-25) \\  \end{gathered}

I hope this helps you

Factorise x^2+9x+18 and hence solve x^2+9x+18=0
lana [24]
x^2+9x+18\\\\9x=3x+6x\\18=3\cdot6\\\\x^2+9x+18=x^2+3x+6x+18=x(x+3)+6(x+3)=(x+3)(x+6)\\\\x^2+9x+18=0\iff(x+3)(x+6)=0\iff x+3=0\ or\ x+6=0\\\\x=-3\ or\ x=-6
