*4. What is the value of (-ab)(a) when a = -2 and b = 3?
(A)
-12
(B) -6
(C)
(D) 12

(D)  12

Step-by-step explanation:

Plug in the given values into the expression.  a = -2  b = -3

(-ab)(a)

[-(-2)(-3)](-2)

(-6)(-2)

12

no i do not : ( what is it?

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
