16. which properties of arithmetic are used
in the following equation? select all that
apply.
(8 + 2) - (2 x 3) = 2(4 + 1) – (3 x 2)
a. commutative property of
multiplication
b. associative property of multiplication
c. commutative property of addition
d. associative property of addition
e. distributive property

  a. Commutative Property of Multiplication

  e. Distributive Property

Step-by-step explanation:

The distributive property lets you rewrite (8+2) as 2(4 +1).

The commutative property of multiplication lets you swap the order of operands to rewrite (2×3) as (3×2).

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent
