We must use PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction
Start with the given equation.
Start by solving the brackets ( ).
This means you need to solve the parentheses ( ) first.
Multiply .
Finish solving the brackets by subtracting.
Solve the exponent next.
Multiply .
Finally, add.
Answer:
Option A: 12
Step-by-step explanation:
From the image of the triangle given, we can see that:
XM = ZM
We are given that:
XM = 2x + 2 and ZM = 4x - 8
Thus;
2x + 2 = 4x - 8
Rearrange to get;
4x - 2x = 8 + 2
2x = 10
x = 10/2
x = 5
Thus, XM = 2(5) + 2
XM = 12
2.

Answer: A
Step-by-step explanation: though they did phrase it in a very weird way, and I would suggest to you to make sure your formatting of your question is understandable, A demonstrates distributive property. you can imagine this as two little arrows going from the multiplier outside the parentheses, to each number inside them. this property is used a Lot in basic algebra and using variables. basically, instead of adding inside the parentheses first, and then multiplying that answer by the outside number, you just multiply the outside number by each number inside the parentheses Individually. and then follow through with the operation. this can get confusing if subtraction or negatives are involved, but I'm sure you'll figure it out :)
