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:
No because when you set it up it would be 11/9.4 which equals 1.17
Then you do the other side, 10/8.4 which equals 1.19
And 1.17 doesn't equal 1.19 so they are not similar
A=p(1-r)^n
A=24,000×(1−0.09)^(5)
A=14,976.77
