First question:
4(3x-5) + (2x -2)(4 + 3x-5)
Simplify -----> 12x - 20 + (2x-2)(3x-1)
Multiply the second part -----> 12x - 20 + 6x^2 -8x + 2
Combine like terms --------> 6x^2 + 4x - 18
Each side of the addition sign represents one of the rectangles above which is then added to get the area of the entire figure.
Second question:
The average is the summation of each data value divided by the number of data values. So it would be
(4 + 5 + 9)/ 3
Simplify ------> 18/3
Divide --------> 6
The answer would be 34. The pattern looks like they are adding the sum to the next expression. So 21+5+8=34. Hope I could help!!:-)))
Your correct answer is option B
Answer:
the answer to this question is 18....to complete this you have to multiple first then add
(Sorry.. im kind of confused by this question...
Answer:
Solving the inequality 
we get 
Option D is correct option.
Step-by-step explanation:
We need to solve the inequality and find value of x
Solving the inequality for finding value of x, we will keep x on left side of inequality and all other terms on the right side.
Adding 2 on both sides
Now, we will divide 3 on both sides
So, we get x < 2
Solving the inequality we get
Option D is correct option.
