Step-by-step explanation:
You can't use quadratic formula in this
Given P=$3000
R=10%
And double of P means A=$6000
Now , we know that
A = P×R×t÷100
6000=3000×10×t÷100
6000×100÷30000 =t
20=t
The Answer is 20 Yrs if rate was for year
Answer:
x=-14
Step-by-step explanation:

(idk if this is correct but i hope it helps)
Answer:
Angle A = 75°
Angle B = 75°
Angle C = 30°
Explanation:
If AC is congruent to CB, from figure given we have angle A = angle B.
Angle A = 3x + 18
Angle B = 7x - 58
Angle C = 2x - 8
We have,
3x + 18 = 7x - 58
4x = 76
x = 19
So,
Angle A = 3*19 + 18 = 75°
Angle B = 7*19 - 58 = 75°
Angle C = 2*19 - 8 = 30°
X=7
STEPS:
6x+3 = 5x+10
-5x -5x
x+3 = 10
-3 -3
x=7
