13 x (15 + 7) ie 13 x 22 = 286
or 13 x 15 = 195, 13 x 7 = 91, 195 + 91 = 286
Yes that is correct
28
It is a quadratic expression which when factored is (2y+3)(y+5)
x2+2x-15 = (x+5)(x-3) when factored
It is a quadratic expression and is (x-3)(x+5) when factored
The expression 15-t plus 8t-13 simplifies to 7t + 2.
'y' is a variable. '15' is not. [ y+15 ] is an expression in one variable.
-13
Yes that is correct
An expression equal to 15 + 35, using distributive property, is 5(3 + 7). Under distributive property, 5*3=15 and 5*7=35.

Good work ! Did you have a question you wanted to ask ?
15 + 13 + 11 = 39
17 plus 15 plus 13 equals 45.
It is: 13/15 plus 1/13 = 184/195
Without an equality sign the given expression is not an equation but it can be simplified to: W-15
n plus 15.n plus 15.n plus 15.n plus 15.
