To find the perimeter of a polygon, simply add the sides.
Here, the sides are: a, a+1, a+2, and 3(a+3)
So,
Now, do the distributive property and combine like terms,
The answer is 6a + 12. Hope this helps and have a terrific day!
<span>The length of a rectangle is 5 units longest than its width. which if the following represents its area in square units?
</span>The length of a rectangle is 5 ft more than its width" means that the length is x+5 units. <span>Since "its area is 84 square feet", we know that x(x+5)=84</span>
C is the answer to your problem have a good day
The x intercept is -12 and it represents the amount of money she started with.
the y intercept is +3 and it represents the amount of money she has now.
the slope is positive and it represents the amount of money shell get in the future
The answers are revealed by subtracting the right side of the equation from both sides.
(a) (2x+3x-6) -(10+4x) = 0
... x -16 = 0 . . . . one solution; neither
(b) (17+5x) -(23+4x-6+x) = 0
... 0 = 0 . . . . . . . an infinite number of solutions; an identity
(c) (7x+4) -(5x+8+2x-10) = 0
... 6 = 0 . . . . . . . no solutions; a contradiction
