81 - 35+30 (55) = 26 therefore 26cm is ur final answer
Answer:
y=x is the correct answer
Explanation:
A linear equation is an equation between two variables that gives a straight line when plotted on a graph.
Why the other ones are incorrect:
y=√x gives a radical function graph
y=x^3 gives a cubic graph
y=x^2 gives a parabola
Answer:
4
Step-by-step explanation:
Answer:
- table: 14, 16, 18
- equation: P = 2n +12
Step-by-step explanation:
Perimeter values will be ...
rectangles . . . perimeter
1 . . . 14
2 . . . 16
3 . . . 18
__
The perimeter of a figure is twice the sum of the length and width. Here, the length is a constant 6. The width is n, the number of rectangles. So, the perimeter is ...
P = 2(6 +n) = 12 +2n
Your equation is ...
P = 2n +12 . . . . . . . . perimeter P of figure with n rectangles.
_____
<em>Additional comment</em>
You may be expected to write the equation using y and x for the perimeter and the number of rectangles. That would be ...
y = 2x +12 . . . . . . . . . perimeter y of figure with x rectangles
