So remember that in a quadratic equation there is a type of quadratic equation of the form ax^2+bx+c=0 so to find what values of a, b, and c you need for the quadratic formula, you need to look at your equation and label a, b, and c. In this equation a=6, b=5 and c=-4. So for the quadratic formula you would use a=6, b=5 and C=-4. I hope this helps!!!!!
B: 914-20(27.80)=X, multiply: 20(27.80)=556, 914-556=$358 :A.
C: 914-27.80=$886.20 :)
Let's solve for x.
x
+
4
y
=
(
14
)
(

)
x
+
7
y
Step 1: Add -42x to both sides.
x
+

Step 2: Add -4y to both sides.
−

Answer:
The last one..Number 4
Step-by-step explanation:
When u add the two sides it's supposed to be larger than the bigger side
so 13+20 is smaller than 34
