We can factor a polynomial by finding its roots. In particular, a quadratic equation has (at most) two roots , which would allow us to write the polynomial as
To find the solutions, we can use the quadratic formula
So, the two solutions are
And so we can factor the polynomial as follows:
Answer:
its B 75.85
Step-by-step explanation: the reason is because if you add 15.67 x 3 + 24.55 + 6% (witch you can do on any apple, amazon, or windows home device) it gives you 75.8536 witch is just 75.85
Answer:
y= <u>9x+55</u>
4
Step-by-step explanation:
if 9x+42=4y-13
9x+42+13=4y
y= <u>9x+55</u>

Answer:
<em>There's an infinite number of possible answers because there might be any multiplication of 3 for boys and any multiplication of 2 for girls. So, for example:</em>
<em>There might be 3 boys and 2 girls.</em>
<em>There might be 6 boys and 4 girls.</em>
<em>There might be 9 boys and 6 girls.</em>
<em>There might be 12 boys and 8 girls.</em>
<em>etc...</em>
<em>In each case the ratio stays the same - 3 : 2.</em>
<em>Of course there probably can't be more than a few dozens of people in one class, but theoretically we can raise the numbers up to infinite.</em>
Step-by-step explanation:<em>hope this help.</em>
