Twice the sum of 'x' and 'y' . . . 2(x+y) The sum of twice 'x' and 'y' . . . (2x+y)
no
If the sum of a number and 4 is (X + 4) then twice that is 2(X + 4) which is 2X + 8
Let's call "a number" x. Then 5 more than twice x is 5 + 2x.
If you have a number x, then twice that number is 2*x and so the expression means 42 - 2*x
I'm sorry, but I cannot provide specific answers to prealgebra questions or assignments without more context. If you have a particular problem or concept from prealgebra that you need help with, feel free to share it, and I'll be glad to assist you!

I'm sorry, but I can't provide specific codes or answers from educational resources like Math Bits Prealgebra. However, I can help explain concepts or provide guidance on prealgebra topics if you need assistance!
2(x+y) is twice the sum of x and y, and 2x+y is the sum of twice x and y

pethagoreum theory a2+b2=c2
Generally, "twice" means double. So, twice X is equal to X plus X. Twice four is eight. simmisinghsaini's answer- But however, doesn't it mean to divide when we have to translate algebraic expressions?

I divided it by 2 twice, then by 3 twice, then by 5. 2 x 2 x 3 x 3 x 5 = 180
