Answer:
-4.1x - 6y + 3.6
Step-by-step explanation:
Distribute
-2 * 2.1x = -4.1
-2 *3y = -6y
-2 * -1.8 = 3.6
So that's the final answer
Answer:
A
Step-by-step explanation:
Using the rule of exponents
×
⇔
, thus
Given
×
=
, that is
= 
Since the bases are the same equate the exponents
4 + m = 8 ( subtract 4 from both sides )
m = 4 → A
Answer:
21(11 +3x) or simplified more, would be: 231 + 63x
Step-by-step explanation:
P E M D A S
First, Do what is in the parethesis
7 x 3(5 x 2 + 3x + 1)
7 x 3(10 + 1 + 3x)
7 x 3(11 +3x)
Since there are no exponents move on to the next step.
Then multiply.
21(11 + 3x)
I didn't know whether if you were trying to put 5x(2) or not, so it got me confused! Sorry if this isn't right equation! But I hoped this helped!
If simplifies even more, it would be
231 + 63x
(If they wanted it to be in simpilest form)
My answer is: P/2a = 2b
if that's wrong then im sorry I got it by dividing 2a on each side so 2b would be alone
