Use the distributive property to simplify the expression below: 5t - 2(1 + t)
The number (-2) need to be multiplied with each value inside the brackets. Then simplify the value for t.
First, multiply the first two terms, I am going to change the variable to x if that's okay, just to make it easier. They both mean the same thing. So, 5x multiplied by 1 will give you 5x. Then, multiply your outside terms (-2)(x) will give you -2x Then, multiply the inside terms (-2)(1) which will give you -2. Finally, multiply 5x by x, which will give you \[5x ^{2}\]. Then, simplify the terms. |dw:1347490477866:dw|
You should get \[5x ^{2}+3x-2\]
it has to be one of thes 6t - 2 -3t + 1 3t + 1 3t - 2
5t-2(1+t) 5t-2(1)-2(t) 5t-2-2t 5t-2t-2 3t-2
