The answer is zero
Hopes this helps :)
Answer: Option 'D' is correct.
Explanation:
Since we have given that
"Three times the number m plus twice the quantity n plus 5 is equal to 20"
So, Equation becomes
As it is said that
three times the number m i.e.
twice the quantity n plus 5 i.e.
Plus both the quantity i.e.
and make them equal to 20 i.e.
Hence, Option 'D' is correct.
B. 81 because the square root of 81 is 9
It would help to find the surface area now, double the dimensions, find the new surface area, and compare.
The surface area of a cylinder is:
2 * pi * r^2 + 2 * pi * r * h
So, the surface area is:
2 * pi * 64 + 2 * pi * 4 = 136 pi
Double the dimensions:
2 * pi * 256 + 2 * pi * 16 = 544 pi
544 pi divided by 136 pi = 4
So, the answer is 4.
Answer:
B: Using x and y factor results in an expression of greater value than using x and y as terms.
Step-by-step explanation:
For her first expression, x and y are factors;
xy
For her second expression, x and y are written as terms;
x + y
For x and y are both negative integers, then;
-x * -y = xy ............... 1
-x + (-y) = - x - y
= - (x + y) .............. 2
Therefore, the value of x and y factors is greater than that when x and y are as terms. Thus the correct option is B.
