Answer:
Step-by-step explanation:
If you factor the expression 7a+21 you can get:
7 × (a+3)
Answer:
B
Step-by-step explanation:
Bbbbbbbbbbbbbbbbbbbbbbbbbb
The exponential function is given in the form

where a is the initial value and b is the multiplicative rate of change
So lets plug the first two values of the table in this function , we get
or

Now plug second

Divide equation 2 by equation 1

On simplifying we get

or

So the multiplicative rate of change of the function is

Answer: The sum of 75.2+(57.376+24.8) is 157.376.
Explanation:
The commutative property of addition states that,

The associative property of addition states that,

The given expression is 75.2+(57.376+24.8).
First use commutative property of addition in the parenthesis.

Now use associative property of addition.

Now simplify the expression,


Therefore, the sum of 75.2+(57.376+24.8) is 157.376.
