Answer: The height of each fir tree is 9 meters, and the height of each pine tree is 12 meters.
Step-by-step explanation:
Let x= height of each fir tree, y = height of each pine tree.
As per given, we have
x+y = 21 (i)
4x=y+24 (ii)
From (ii),
(iii)
Add (i) and (iii), we get
Put value of x in (i), we get
Hence, the height of each fir tree is 9 meters, and the height of each pine tree is 12 meters.
Answer:
Step-by-step explanation:
The law of indices can be used to simplify mathematical expressions involving arithmetical operation on variables with powers.
x 
= 
Thus, the given expression can be simplified as follows:
a³b² a²b = a³ x a² x b² x 
= 
x 
=
Thus,
a³b² a²b =
It would be C because it’s asking you to multiple 3/4 by 3/4 sense there is a 2 exponent. And in order to multiply fractions you multiply across the top and bottom and then simplify. Sense c is already simplified that would be your answer. 3 x 3
4x4 9/16 or c
Answer:
Option 4: y > 2x
x + 2y < -8
Step-by-step explanation:
Taking first equation:
y > 2x
Putting x = 0
y > 0
Putting y = 0
0 > x
So the blue line in drawn according to first equation.
Taking second equation:
x + 2y < -8
Putting x = 0
2y < -8
y < - 4
putting y = 0
x < -8
So the red line is drawn accordingly.

Answer:
4 pi
Step-by-step explanation:
diameter = 2r
4 =2r
r =2
area = pi × (r)^2
= pi × 2^2
= 4 pi
