Rewrite the expression without using grouping symbols. y • 4 + y • z

4y + yz

Step-by-step explanation:

the grouping symbols can be parentheses, brackets, or in this case a sign of multiplication ·

you have the expression

y · 4 +y ·z

to eliminate the symbol  · from the first term you just do the multiplications:

y multiplied by 4 is equal to 4y

and to eliminate the symbol  · from the second term, since we don't know the values to y and z, we let them indicates as yz, because the simple fact of two variables written together is indication of a multiplication.

So the result is:

4y + yz

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
