Answer:
4x²+12xy+9y²
(2x+3y)²
=(2x+3y)*(2x+3y)
2x *2x , 2x *3y , 3y* 2x ,3y* 3y
=4x²+12xy+9y²
Answer:
400 J
Step-by-step explanation:
Kinetic energy = ½ mv²
mass = 50 kg
velocity = 4 m/s
Kinetic energy = ½×50×(4)²
= ½×50×16
= 50×8
= 400 J
Option Four
Answer: 28.8°
<u>Step-by-step explanation:</u>
∠A = 5(∠B) + 7.2°
∠B = ∠B
Since they are on a straight line, they form a linear pair (sum = 180°)
∠A + ∠B = 180°
Use Substitution:
5(∠B) + 7.2° + ∠B = 180°
Add like terms:
6(∠B) + 7.2° = 180°
Subtract 7.2° from both sides:
6(∠B) = 172.8°
Divide both sides by 6:
∠B = 28.8°
Answer:
x+8y
Step-by-step explanation:
common factor it by 3
so the answer is
x+8y
C, because once you add the texture up
