1times 5 i need with this and backward math

-5

Step-by-step explanation:

You should get negative 5 because first you multiply and add a sign.

So for this question, you needed to add a negative sign because there are 2 negative signs and 1 positive. ( -,-,+) so if you do -1 x5, sinse you used one negative sign for the -1 and a positive sign for 5, you are left with a negative sign. So that is why you need to add a negative sign before our answer 5. on this question.

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6
