Hello,
Five sixths of forty two is = 35.
The correct answer is C, x is greater than -5. In order to solve this, you have to solve for x by simplifying both sides of the equation. Then you have to isolate the variable. Hope this helped!
I prefer to use compatible numbers because by using this method it is easier to make a sum mentally. This is true because compatible numbers are close in value to the actual numbers. For a better understanding, let's take an example:
Suppose you have two numbers, namely 640 and 40. These two numbers are compatible for division because:
64 ÷ 4 = 16
So, we have used mental arithmetic to solve a more complex problem.
The correct option is (B) 4x^2 + 18x + 18
Explanation:
The area is given as:
(3+2x)(6+2x)
To find the polynomial just simplify it.
3(6+2x) + 2x(6+2x)
18 + 6x + 12x + 4x^2
4x^2 + 18x + 18
