Parentheses can be eliminated using the distributive property
-6x +6(3x -4xy) = -6x +18x -24xy
Like terms (those with the variable x only) can be combined
x(-6+18) -24xy = 12x -24xy . . . . . simplified
_____
In some cases, you may be interested in factoring the expression. 12x is a common factor for the two terms, so another way to write this expression is
... 12x(1 -2y)
Answer: 17, 19, 21 and 23
Step-by-step explanation:
Let x-3, x-1, x+1 and x+3 be 4 consecutive odd numbers.
Now,
According to question, their sum is 80.
x-3 + x-1 + x+1 + x+3 = 80
4x = 80
x = 20
Four consecutive odd numbers are,
x-3, x-1, x+1 and x+3
20-3, 20-1, 20+1 and 20+3
17, 19, 21 and 23
Answer:
Option D : 32.15 square centimeters is the correct answer.
Step-by-step explanation:
Given that:
Area of the circle can be find by the following formula.
Area of circle = pi * radius * radius
The radius of circle in the given figure is 3.2 cm
Area of circle = 3.14 * 3.2 * 3.2
Area of circle = 32.1536 square centimeters
Rounding off to two decimal places.
Area = 32.15 square centimeters
Hence,
Option D : 32.15 square centimeters is the correct answer.
