Step-by-step explanation:
3x^2-(24+9)x+72=0
3x^2-9x-24x+72=0
3X(x-3)+24(x-3)=0
(x-3)(3x+24)=0
Answer:
1.5
Step-by-step explanation:
a : b = 1 : 12/5
Area of a circle = πr²
Where : = π = pi = 22/7
R = radius
Let the radius of circle a = 1
Area of circle A = 1π
Radius of circle A = square root of 12/5 = 1.5
The circumference of a circle = 2nr
n = 3.14
circumference of circle A = 2 x n x 1 = 2n
circumference of circle B = 2 x n x 1.5 = 3n
ratio of circumference = 3n / 2n = 1.5
There’s are ratio which would be 8/10. 12/x should equally 8/10. So it would be 14 tiles long.
18 because 15÷0.75 is 20. 20×.90 is 18.

The interest rate would be 20%.
The formula is derived from the compound interest formula

.
We want to isolate r in this equation to rewrite the formula. The first thing we would cancel, outside parentheses, would be p; divide both sides by p and we have

We want to cancel the exponent, t, next. We can raise a power to its reciprocal to undo it; for example, raising a squared amount to the 1/2 power will undo the exponent. We will raise both sides of this to the 1/t power:

Now we cancel the 1 by subtracting, giving us

Using this formula, we plug in 3600 for A, 2500 for p and 2 for t:
