(3x+4)(2x+1)
If the question asks you to find roots/solutions:
3x + 4 = 0
3x = -4
x = -1.33333333
2x + 1 = 0
2x = -1
x = -0.5
Answer:
5%
Step-by-step explanation:
The computation of the two rates of interest is shown below;
The interest rate for $3,000 be x%
And, for $4,500 the interest rate is (x -2%)
The total interest earned is
= x% of $4,500 + (x - 2)% of $4,500
So, the two rates of interest is
x% of $4,500 + (x - 2)% of $4,500 = $435
30x + 45(x - 2) = $435
30x + 45x - 90 = $43
75x = $25

Answer:
6 : 5
Step-by-step explanation:
Volume of a cube = s^3
5^3 = 125
Surface area of a cube = 6s^2
6(5^2) = 6(25) = 150
150 : 125
30 : 25
6 : 5
The computation shows that the value of the indices will be C. 4.2 × 10^5
<h3>How to calculate the value?</h3>
From the information given, the value will be:
= (7 × 10³) × (5.4 × 10⁴) / (9 × 10)²
It should be noted that in indices when it's multiplication, the powers will be added and subtracted when it's division.
Therefore,
.= (7 × 10³) × (5.4 × 10⁴) / (9 × 10)²
= 4.2 × 10^5
In conclusion, the correct option is C.
