The perimeter is 6x + 12, and a model example is attached.
All three sides of an equilateral triangle are the same, so multiply the side length by 3 to find the perimeter.
3(2x + 4)
Now distribute the 3.
3 * 2x + 3 * 4
6x + 12
Answer:
C
Step-by-step explanation:
The blue line is the one that that slants from lower right to upper left. It has a negative slope as in - 1/2. The line is solid so that means the values of the line are included in the expression.
The area covered is purple, so y is less than the y values of the line. C is the only value that shows the paragraph above.
But we have to check the other inequality just to make sure you are right. y > 2/3 x - 4. The line is not included, so C is your answer.
Step-by-step explanation:
Simplify the following expression then state the property used:
9^-2
Property:
Given,
9^-2
For any real numbers a and b a, b ≠ 0, and for any two positive integers, n and n
a^-m
=> 1/a^m [By doing reciprocal]
So,
9^-2
=> 1/9^2
=> 1/(3^2)^2
=> 1/(3^4)
=> 1/(3*3*3*3)
=> 1/81. Ans.
