How to work out the width when you only have the length and height (it's of an television)

Yes. there is a constant ratio of number of calories to gram of protein.12/3=24/4=32/8=44/11=4

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
