What property is illustrated by this question? 0.2x + 1.3 + 3.9x + 9.75 A.
arithmetic fact
B.
associative
C.
distributive
D.
commutative

The associative property is illustrated by this question ⇒ B

Step-by-step explanation:

Commutative Property states that you can move numbers around and still arrive at the same answer

For addition, a + b = b + a

For multiplication, a × b = b × a

Associative Property states that you can re-group numbers and you will get the same answer and the commutative property

For addition, (a + b) + c = a + (b + c)

For multiplication, (a × b) × c = a × (b × c)

Distributive Property  states that the sum of two numbers times a third number is equal  to the sum of each addend times the third number

(a + b) × c = a × c + b × c

∵ The question is 0.2 x  + 1.3 + 3.9 x + 9.75

- To solve it you will add the like terms so you must group them

∴ 0.2 x  + 1.3 + 3.9 x + 9.75 = (0.2 x + 3.9 x) + (1.3 + 9.75)

- This is the associative property because you re-group the numbers

∴ The associative property is illustrated by this question

for this case we have the following expression:

to solve, we rewrite the expression as:

we apply double c and we have:

thus, the quotient is 48.

so, patel found a wrong ratio and the multiplication was incorrect.

option d

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
