Answer:

Second from the top

The answer you have selected:

40:8 , 50:10, 60:14, 90:18

Proportions can be viewed as fractions:

40/8, 50/10, 60/14, 90/18

Now we have to simplify these fractions

5 , 5 , 4.3, 5

Unfortunately, they do not all come out to the same number, so this answer is incorrect

The second answer from the top:

4/2 , 7/3.5, 8/4, 10/5

These all equal 2 when simplified

2, 2, 2, 2

This shows a proportional relationship between x and y. If you would like to continue to make sure the bottom two are incorrect, you can use the steps that I have used for the first two. Hope this helps :)

2x+3x^2(4x-5)<br> please helpppp asap
Aliun [14]

Here's my step-by-step explanation:

We're just gonna factor.

If your teacher has spoken of FOIL, then he/she has probably said that it means First Outer Inner Last and that it helps with distributing problems like these.

Right, so let's get to it.

2x+3x^2 (4x-5)\\2x(4x-5)+3x^2(4x-5)\\2x(4x) + 2x(-5) + 3x^2(4x) + 3x^2(-5)

Can you see the FOIL method being spread out here? Let's keep going.

2x(4x) + 2x(-5) + 3x^2(4x) + 3x^2(-5)\\8x^2 + (-10x) + 12x^3 + (-15x^2)\\12x^3 + 8x^2 - 15x^2 -10x\\12x^3 -7x^2 -10x

Hope this helps, and let me know if I made a mistake! ^_^
