The answer oils be 2 square root 2 because 4 times 2 is 8 and because the square root of 4 is 2 you would move that 2 to the outside and keep the other two on the inside of the square root.
Step-by-step explanation:
1. multiply put the brackets
so it'll be 2d+6+3d-9
2. put into into like terms
2d+3d is 5d
6-9 is -3
There fore the answer is option B where it will be 5d-3
Hope this helps !!!
Have a nice day :)
The mean of the sample given by 44,22,11,17,21 will be given by:
the sum of x's will be:
44+22+11+17+21
=115
n=5
therefore the mean will be:
μ=115/5
=23
Answer:
The number of solutions of an equation is dependent upon the total number of variables contained in it. Thus, the system of the equation has two or more equations containing two or more variables. It can be any combination such as 1. 2 equations in 3 variables 2. 6 equations in 4 variables, and so on Depending on the number of equations and variables, there are three types of solutions to an equation. They are 1. Unique Solution (One solution) 2. No solution 3. Infinite Solutions (Many solutions) The term “infinite” represents limitless or unboundedness. It is denoted by the letter ” ∞ “
