3) Which property is used in the following: 4 x (5 + 7) = 4 x 5 + 4x7
earnstyle [38]

Answer:

3) D

4) B

5) A

6) 2 (x + 7)

Step-by-step explanation:

3)  

D. Distributive Property

The distributive property of multiplication over addition can be used when you multiply a number by a sum.

4)

B. 2 + 8 = 8 + 2

The word "commutative" comes from "commute" or "move around", so the Commutative Property is the one that refers to moving stuff around.

5)

A. 4 x 1 = 4

The "Multiplicative Identity" is 1, because multiplying a number by 1 leaves it unchanged: a × 1 = 1 × a = a.

6)

3 ( x + 3) - X + 5

3x + 9 - x + 5

2x + 14

2 (x + 7)

Consider lim t → 0+ ( −2 sin(4t) sin(4t) + 2 t cos(4t) ) . using a table of values, the limiting value is
Andrej [43]
Since this is not a rational function (with undetermined values in the denominator), but just a normal expression, we can just substitute t with the value toward which the function is approaching. Since this is a continuous function, it doesn't matter from which side it's approaching 0. In this case, let t=0, then sin(4t)=0, cos(4t)=1, then -2 sin^2(4t)+2tcos(4t)=0.
