In this question ,it is given that
The penny size of a nail indicates the length of the nail. The penny size
d is given by the literal equation

where n is the length (in inches) of the nail.
In the first part we have to solve for n .
And for that firt we add 2 to both sides

Now we divide both sides by 4, that is

Part b.
When d=3

When d =6, we will get

When d =10, we will get

Answer:
7/25
Step-by-step explanation:
The fraction is not reduced to lowest terms. We can reduce this fraction to lowest terms by dividing both the numerator and denominator by 4. 4 is the Greatest Common Divisor (GCD) or Greatest Common Factor (GCF) of the numbers 28 and 100.
1) 5t^2 (1 + 6t)
2) 4x^3y^5 (5x + 2y)
3) (5r + 6x)(5r - 6x)
4) (x + 10)(x - 10)
5) (x - 3)^2
6) (x -5)(x - 3)
7) 3(16r^3 + 9)
8) 8(c^3 + 8d^3)
9) (2r - 125)(4r^2 + 250r + 15625)
10) (c + 3)(c - 1)
Answer:
Step-by-step explanation:
When the exponent is attached to the trig function like that, its essentially the same thing as taking the entire function to that power.
tan^2(x) = (tanx)^2
