n is less than or equal to 5. This is because you must isolate the variable (n) by adding 7 to cancel/move it to the right side.
3k + 30m (I think that’s what it’s asking for!)
Answer:
6.3 years
Step-by-step explanation:
The formula for depreciation is
Where P is the initial value, A is final value, t is duration in years and r is rate in deximal point. Substituting 55, 500 for P and 20, 000 for A, 0.15 for rate, r then
Therefore, it requires about 6.3 years
The area of the blanket - 24 ft²
length being longer than the width means that blanket is a rectangle
width of the blanket = x
length of blanket = x +2
area = length * width
area = x * (x+2)
= x² + 2x
since area = 24
x² + 2x = 24
x² + 2x - 24 = 0
we have a quadratic equation and we need to now solve for x
x² + 6x - 4x - 24 = 0
x (x + 6) - 4(x + 6) = 0
(x-4) (x+6) = 0
x-4 = 0 or x + 6 = 0
x = 4 or x = -6
x could be either 4 or -6. since dimensions cannot have negative values,
x ≠ -6
therefore x = 4
width = 4 ft
length = 6 ft
