How do I solve this and what are the rules to solving this

334

(Pemdas rules apply)

Step-by-step explanation:

In order to sole this equation we must use what is called "PEMDAS" which stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. This is also known as the order of operations which is the correct sequence of an equation (From left to right).

Now solving the equation itself:

4 [ 2.5 + 3 ( 20 + 7 ) ] <--- First add 20 and 7.

4 [ 2.5 + 3 ( 27 ) ]   <--- Then multiply 27 by 3.

4 [ 2.5 + 81 ]   <--- Then add 81 and 2 together.

4 [ 83.5 ]  <--- Multiply 83.5 by 4.

= 334

Therefore, our final answer is 334, I hope this helps :)

mean, 40.6

step-by-step explanation:

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
