Answer:
right
Step-by-step explanation:
(x+2)/(x) + (x-3)/(x+2)
Common denominator x(x+2)
Reduce both to common denominator:
x+2)/[x(x+2)] + (x-3)/[x(x+2)] ===> [(x+2)² + (x-3)] / [x(x+2)]
= [x²+4x+4+x-3] / [x(x+2)]
=[x²+54x+1] / [x(x+2)]

Answer:
34072.3 in³
Step-by-step explanation:
Step 1
The circumference of its base is 125.6 inches.
C= pi x diameter
Find the radius of the base
C/ π = Diameter
Diameter = 125.6 in/2
= 62.8 in
Step 2
The height of the cone is 33 inches.
Radius = Diameter/2
Radius = 62.8 in/2
= 31.4 in
Volume of a cone: V = (1/3)πr²h
= 1/3 × π × (31.4)² × 33
= 34072.33162 in³
Approximately = 34072.3 in³
Therefore, the volume of Nuala's cone is 34072.3 in³.

Answer:
The right answer is : B)
___________________
Step-by-step explanation:
(5x+20)+(x+40)=180 ⇔ 6x + 60 =180 ⇔ 6x=120 ⇔ x=20
Then 5x+20 = 5(20)+20 = 120
x+40 = 20+40 = 60.
……In conclusion……
5x+20 = 120°
x+40 = 60°.
