45x5=225
To solve this, multiply the two numbers together. You can use a calculator or you can do it by hand: 45 X 5 = 225
To convert F to C, subtract 32, then multiply by 5/9 77-32 = 45 45x5/9 = 25 Going the other way, to convert C to F Multiply by 9/5, then add 32
436 is the best choice for the next number in the sequence because:3x3=9-5=45x5=25-5=2021x21=441-5=436The Pattern: Square the term, then take away 5, add one, and square it again, and so on.
