8m^2+18m+9=0
Multiply 2m by 4m to get 8m^2. Multiply 2m by 3 to get 6m. Multiply 3 by 4m to get 12m. Add the 6m and 12m to make 18m. Multiply 3 by 3 to get the integer 9. Set it all equal to 0.
Explanation:
Step 1) Add

Answer:
s/3
Step-by-step explanation:
The quotient means you divide the two values.
Answer: y = -5x + 20
Step-by-step explanation:
Remember that : y=mx+b
y = (-5)x + b
Now you can plug your coordinates (-7,8) into that equation.
8 = (-5)-7 + b
Solve for b
8 = -12 + b
Add +12 to both sides of your equation:
20 = b
Now, your new equation is:
y = -5x + 20
If you simplify 2/10 to get 1/5 then you can add the two together to get 4/5, so that would leave 1/5 for richard
