Answer 1
Answer:

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)

Answers

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'.

Polygon MNOPQ is dilated by a scale factor of 0.8 with the origin as the center of dilation, resulting in the image M′N′O′P′Q′. The coordinates of point M are (2, 4), and the coordinates of point N are (3, 5).What is the slope of M′N'?

Answers

First, we calculate the slope of MN:
= (5 - 4) / (3 - 2)
= 1
Dilation does not affect the slope of a line; therefore, the slope of M'N' is also 1.
Thank you for posting your math question here at brainly. The slope of M'N would be 1. Below are the choices that can be found elsewhere:

a. √2
b. 1
c. √3
d. √1/2

Below is the solution 

= (5 - 4) / (3 - 2)
= 1
