The expression which represents half the sum of five and a number b is (b+5)/2.
It is when the answer, when 2 things are multiplied, is the same as when they are added. For instance, 2*2=2+2
the product of 8 and the sum of 10 and -7
x = 22
multiply by one if ur looking for the sum and divide by one if look ing for the product, easy
As an expression it is: 8x+14
(a + b)/(xy)
" 3x + 5 " does.
