Answer: 
Step-by-step explanation:
8 x 14 x 21 = 2352, so:
√8⋅√14⋅√21 = √2352
√2352 in simplest form is 28√3
I hope this helps!
Answer: A) 23
Step-by-step explanation:
3^2 + ( 6 - 2 ) ⋅ 4 -6/3
3^2 + 4 ⋅ 4 -6/3
9 + 4 ⋅ 4 -6/3
9 + 16 -6/3
25 - 6/3
75/3 -6/3 = 69/3
69/3 = 23
Answer:
1. 18.85in
4. 25.13m
Step-by-step explanation:
I got you
So to find the circumference of any circle we use the equation 2pi(r)
2(3.1415)(3)= 18.85in for the first one because radius is half of the diameter which is 6 so half of 6 is 3
For 4. 4m is actually the radius so just plug that into the equation 2pi(4)=25.13m
9514 1404 393
Answer:
6/5
Step-by-step explanation:
The slope formula is useful for finding the slope.
m = (y2 -y1)/(x2 -x1)
m = (-1 -11)/(-5 -5) = -12/-10
m = 6/5
The slope of the line through the given points is 6/5.
Answer:
After finding like terms and solving, we get 
Step-by-step explanation:
We need to find like terms and simplify the expression 
Like terms: The terms who have same variable and exponent are called like terms.
So, Combining like terms and solving:

So, after finding like terms and solving, we get 
<u><em>Note: In the question given we have - and + sign with the term 5x</em></u> i.e 4- 2x + x^2 -+ 5x + 12 + 2x^2
I have solved using +5x, but if the term is -5x then the solution will be:

So, the answer will be:
