Answer: 40x^4 + 56x^3 − 16x − 14

Step-by-step explanation:

1. For any two functions, the derivative of the product of two functions is the first function times the derivative of the second plus the second function times the derivative of the first.

2. The derivative of a polynomial is the sum of the derivatives of its terms. The derivative of a constant term is 0.

3. Simplify

4. Multiply 4x^2 + 7x^1 times 6x^2

5. Multiply 2x^3 - 2 times 8x^1 + 7x^0

6. To multiply powers of the same base, add their exponents.

7. Simplify

8. Combine like terms

9. For any term t, t^1 = t

10. For any term t except 0, t^0 = 1

Answer: 37.9 inch the length of lead stripping .

Step-by-step explanation:

Given ,

Sides of windows are $6\frac{4}{5}$ and $15\frac{14}{25}$

$= (6\frac{4}{5} + 15 \frac{14}{25} ) * 2\\ \\=\frac{34}{5} + \frac{389}{25} * 2\\\\ \frac{170}{25} + \frac{389}{25}* 2 \\\\= \frac{559}{25} * 2\\\\= \frac{948}{25} \\\\= 37.9 inch$

So , the answer is 37.9 inch
