Answer:
x=12 ; y=8
Step-by-step explanation:
8x+13=11x-23(2 opposite side of a parallelogram is equal)
move the x terms to the left side.
8x-11x=-23-13
-3x=-36
3x=36
x=12
2y+12=4y-4(2 opposite side of a parallelogram is equal)
move the y terms to the left side
2y-4y=-4-12
-2y=-16
2y=16
y=8
Answer:
Compare price and quality

Hey there!!
In order to solve this question, we take the area as 196 as these are the total number of plants to cover a specific place.
The formation must be in a square formation
area of a square = ( s ) ²
s = side
or the number of plants in a row
s² = 196
s = √196
s = 14
There are 14 plants in each row
Hope my answer helps!

Change the order of integration. The region over which you're integrating can be equivalently described by the set of points in the plane,
.
Then the integral becomes
![\displaystyle\int_{y=0}^{y=1}\int_{x=0}^{x=y}\cos y^2\,\mathrm dx\,\mathrm dy=\int_{y=0}^{y=1}y\cos y^2\,\mathrm dy](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Cint_%7By%3D0%7D%5E%7By%3D1%7D%5Cint_%7Bx%3D0%7D%5E%7Bx%3Dy%7D%5Ccos%20y%5E2%5C%2C%5Cmathrm%20dx%5C%2C%5Cmathrm%20dy%3D%5Cint_%7By%3D0%7D%5E%7By%3D1%7Dy%5Ccos%20y%5E2%5C%2C%5Cmathrm%20dy)
Substitute
