Answer:
x = 1.47 or x = -7.47
Step-by-step explanation:
x²+6x+9=20
This is a quadratic equation
x²+6x+9-20=0
x²+6x-11=0
Step 1 : Write the quadratic formula
x = <u>-b±√b²-4(a)(c)</u>
2a
Step 2 : Substitute values in the formula
a = 1
b = 6
c = -11
x = <u>-6±√6²-4(1)(-11)</u>
2(1)
x = <u>-6±√80</u>
2
x = -3 + 2√5 or x = -3 - 2√5
x = 1.47 or x = -7.47

Answer:$6.11 per bag
Step-by-step explanation: The total of both the apples and ice cream is 55.68. Since we’re just trying to find the total price of apples, we’ll subtract the total price of ice cream. 55.68-6.80=48.88. Now we’ll divide $48.88 by 8, since there are 8 bags. That leaves us with $6.11
C. 4x + y = 21
4(3) + 9 = 21
12 + 9 = 21
21 = 21
