The answer would be 2x^2+2x-4
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
Well the average would change from 85 to 85.4

Answer:
50°, 130°
Step-by-step explanation:
All measures are in degrees. Let x represent "one angle". Then the other is (180-x) and we can write the relation ...
3x = 20 +(180 -x)
4x = 200 . . . . . . . add x, collect terms
x = 50 . . . . . . . . . . one angle
180 -50 = 130 . . . .the other angle
The measures of each angle are 50° and 130°.
