Given: (3.2 x 103) + (5.78 x 105) Solve the problem. Show and explain all of your work. ??????
qaws [65]
Simple....

you have: (3.2*103)+(5.78*105)

You want to simplify it..but first remember your order of operations...

1.) Remove the parentheses-->>

(3.2*103)=329.6

and

(5.78*105)=606.9

Which leaves you with...

329.6+606.9=

=936.5

Thus, your answer.

ad-work [718]

Answer:

An example below

Step-by-step explanation:

5(4a + 7(a + 2b))

First simply the inside bracket using distributive property:

7(a + 2b)

7(a) + 7(2b)

7a + 14b

5(4a + 7a + 14b)

5(11a + 14b)

Use distributive property again

5(11a) + 5(14b)

55a + 70b
