Option C: 7 hours to build 8 house,
Whenever getting work-time related questions, it is needed to focus that as the amount of work done increases, the time needed to complete also increases.
Given that:
3.5 hours of work is needed to build 4 birdhouses.
Thus as we increase the time twice, the number of birdhouses build by the same person Jasmine will be twice as she got doubletime, thus building 2 times 4 i.e. 8 birdhouses.
Thus we have:
Jasmine takes 7 hours of work to build 8 birdhouses.
Therefore we see that Option C: 7 hours to build 8 birdhouses is correct.

Step-by-step explanation:
multiplying polynomials find the product (2a-1)(8a-5)
The product of (2a-1)(8a-5) is 16a² - 18a + 5.
To find the product of (2a-1)(8a-5), we can use the distributiveproperty. This means that we multiply each term in the first polynomial (2a-1) by each term in the second polynomial (8a-5) and then combine like terms.
Applying the distributive property, we have:
(2a-1)(8a-5) = 2a(8a) + 2a(-5) - 1(8a) - 1(-5)
Simplifying this expression, we get:
16a² - 10a - 8a + 5
Combining liketerms, we have:
16a² - 18a + 5
Therefore, the product of (2a-1)(8a-5) is 16a² - 18a + 5.
In this case, we multiplied each term of the first polynomial by each term of the second polynomial, resulting in four terms. Then, we combined like terms to simplify the expression. The final product is a quadratic polynomial with a leading coefficient of 16 and terms involving the variable 'a'.
