See the diagram in the attached figure
we know that the area of rectangular shaped playground is--> 80*100=8000 m²
the area of the pathway=[(100+2)*(80+2)]-[80*100]=8364-8000=364 m²
the answer is 364 m²
-2y because -8x2y3 divided by xy = -8xy2, 4xy times -2y= -8xy2
You just find the area of the triangle, and do that times 4 that number. The formula for finding the area of a triangle is half the base times the height 3 * 9 = 27. So the area of the triangle is 27 and the area of all 4 of the triangles would just be 27 * 4 = 108. Now for the square. Formula for finding the area of a square is length times width which would be 6 * 6 = 36. So then you do 36 + 108 = 144
So the area of the net is 144M
Answer:
The high of the water is<u> 2 cm.</u>
Step-by-step explanation:
The equation of this volume is:
We know that the volume is 900 cm³. So we just need to put this value in the above equation and solve it for x, which is the height.
Therefore, the <u>high of the water is 2 cm.</u>
I hope it helps you!
Answer:
(x + 2)²
Step-by-step explanation:
x² + 4x + 4 ← is a perfect square of the form
(x + a)² = x² + 2ax + a²
Comparing coefficients of like terms
4 = 2² ⇒ a = 2 and 2ax = (2 × 2)x = 4x
Hence
x² + 4x + 4 = (x + 2)²
