If you want to solve for x
-5x-4=?
add 4 to both sides
-5x=4+?
divide both sides by -5
x=(4+?)/-5
x=-(4+?)/5
Ask which two numbers add up to -11 and multiply to 30?
That would be; -6 and -5
Rewrite the expression using what you have above;
<u>(x - 6)(x - 5)</u>
F(x)=-4(-1)-5
f(x)=4-5
f(x)= -1
-1 is your answer
34/4=8.5
8.5x5=42.5
The answer is $42.50
To solve for c, you divide both sides by -18. If you do that, your answer will be -1/16. So, I think you typed the question wrong. Pretty sure it's the first option.
