jayden used the following steps to simplify the given expression.

-3 + 2(2 + x + 3)

step 1: = -3 + 2(x + 2 + 3)
step 2: = -3 + 2(x + 5)
step 3: = -3 + 2x + 10
step 4: = 2x + (-3) + 10
step 5: = 2x + 7

what property of real numbers was used in step 3?
a)distributive property
b)associative property of addition
c)commutative property of addition
d)associative property of multiplication

Option A -distributive property

Step-by-step explanation:

Given : expression     -3 + 2(2 + x + 3)

Step 1: = -3 + 2(x + 2 + 3)

Step 2: = -3 + 2(x + 5)

Step 3: = -3 + 2x + 10

Step 4: = 2x + (-3) + 10

Step 5: = 2x + 7

In step 3 distributive property is applied i.e. c(a+b)=ca+cb

in step 2- 2(x+5) when we apply distributive property it became

2x+10

Therefore, option A is correct

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
