Answer:
Nuevo perímetro del cuadrado = 24 + 4 = 28 cm. Ejemplo 5: El área de un parque cuadrado es de 225 m2.
Answer:
By SAS rule
Step-by-step explanation:
Required to Prove
ABC is congruent to DEC
Given
C is midpoint of AD and BE
As C is the midpoint of both line segments
AC=CD
BC=CE
and ∠ACB=∠DCE(Vertically opposite angles)
⇒By SAS(side-AC and DC, angle-∠ACB,∠DCE,side-BC and EC) congruency rule
triangle ABC is congruent to triangle DEC
Now, we know that he's charging $12 per session to each of his students, and he has 14 students currently, so his revenue is just 14 * 12 or 168 bucks.
now, let's take a peek as the session price goes up in jumps of 2, from 12, to 14, 16, 18 and so on, as each jumps happen, the students drop by 1, from 14, to 13, to 12 and so on.

notice, the revenue starts off at 168, goes up up, reaches 200 bucks and then starts to drop back down.
thus, that means the U-turn or vertex of that revenue function is at 4,200, namely h = 4, and k = 200

16=x-4
Hope this is what you meant lol
Answer:
a=1
Step-by-step explanation:
The answer to this problem is 1. This is the answer because using PEMDAS, you would first have to distribute -3.
So: 9a+ -6a+12=15
Combine like terms:
3a+12=15
Subtract 12 on each side. 3a= 3
Divide 3 on each side.
a=1
Hope this helps!! :D
