Binomial means there are two terms, so c² − 16 is the answer
mononomial means there is only one term, so -8c is the answer
written in descending form means from the highest degree (exponent) to the lowest, 4x² − 3x + 9 is the answer for question 3.
Question 4: use the same method for question 3, the third term is -7x

Question 5: not sure what this is: 2x2y. Is it 2x²y or 2x2y?
you need to add up the exponent of x and y. In this case, the highest degree is y's 4th power plus x's 1st power, which makes a 5.

Step-by-step explanation:

$3 + \frac{9}{4} = \frac{9}{x+4} \\ \\ \therefore \: \frac{3 \times 4 + 9}{4} = \frac{9}{x+4} \\ \\ \therefore \: \frac{12 + 9}{4} = \frac{9}{x+4} \\ \\ \therefore \: \frac{21}{4} = \frac{9}{x+4} \\ \\ \therefore \:21(x + 4) = 36 \\ \\ \therefore \:21x + 84 = 36\\ \\ \therefore \:21x = 36 - 84\\ \\ \therefore \:21x = - 48\\ \\ \therefore \:x = \frac{-48}{21} \\ \\ \therefore \:x = \frac{-16}{7} \\ \\ \huge \red{ \boxed{ \therefore \:x = - 2 \frac{2}{7} }}\\ \\$

Use pictures or words to explain what shapes can be put together to make a hexagon shape.

GenaCL600 [577]

Triangles are the easiest shape to make a hexagon out of. You can do this by lining up 6 triangles where each base of the triangle lines up.

Sara sells dishwashers. She earns an 8% commission on sales. How much must he sell in order to earn $3000?

andrezito [222]

Well, if we look at a calculator and ask, what is 8% of 3000$ we get the answer of 240 dollars.

3000 - 8% = 2760 therefor we know it removes 240 dollars. So the commission is 240 dollars.
