Answer:
I think it is the second one
Answer:
6x+2
Step-by-step explanation:
The perimeter is all of the sides added together.
We know that in a rectangle, sides that are parallel to each other are the same.
So, to find the expression that represents the perimeter, you have to multiply 2x+1 by 2 and x by 2 and add both of those together.
(2*(2x+1))+(2*(x))
(4x+2)+(2x)
4x+2+2x
6x+2
Answer:
144 carrots
Step-by-step explanation:
Let C stand for the number of carrots that a student can plant.
We are told that carrots may be planted at a density of 9 carrots/ft^2.
Let A be the area, in ft^2, that can be planted with carrots. The area of a rectangle is Base x Length (in feet).
We can therefore write:
C = (9 carrots/ft^2)*A
In the garden shown, the area is A = (4 ft) x (4 ft) = 16 ft^2
C = 9 carrots/ft^2)*(16 ft^2)
C = 144 carrots
the simplified expression would be 81-52y
Answer:
50°
Step-by-step explanation:
Let :
Let the angle = x
Second angle = x + 10
Third angle = x - 10
Sum of angles in a triangle = 180
x + (x + 10) + (x - 10) = 180
x + x + 10 + x - 10 = 180
3x = 180
x = 180 / 3
x = 60
Smallest angle :
x - 10 = 60 - 10 = 50°
