**THIS IS DUE SOON, PLEASE HELP** Lin missed math class on the day they worked on expanding and factoring, Kiran is helping Lin
catch up
Lin understands that expanding is using the distributive property, but she doesn't
understand what tactoring is or why it works. How can Kiran explain factoring to Lin?
Lin asks Kiran to help her factor the expression -4xy - 12xz + 20xw. How can Kiran use
this example to Lin understand factoring?

Given a: b and b: c, find a: b: c. write the ratio in simplest form. a: b=6: 10 and b: c=21: 33

Kevin has a spinner that has 10 equal sections and 2 sections of each color—red, blue, green, yellow, and purple. kevin spins the spinner 180 times. kevin determines about how many times the spinner will land on red or green, and his work is shown below. -kevin has the formula reversed; it should be the total number of sections over the number of red or green sections. -kevin should have used a 4 in the numerator because there are 2 red sections and 2 green sections. -kevin should multiply by the number of sections in the spinner rather than the total number of spins. -kevin calculated the prediction correctly and did not make any mistakes.

15 liters is approximately how many gallons
