Answer:
false
Step-by-step explanation:
the formula for the area of a circle is πr^2
π=3.14
r= 1/2 of diameter = 6
3.14 x 6^2
=113.04cm2
Plug y= x+5 in 3x+y= 25, we have:
3x+ (x+5)= 25
⇒ (3x+x)+ 5= 25 (combine like terms)
⇒ 4x= 25-5
⇒ 4x= 20
⇒ x= 20/4
⇒x= 5
y= 5+5= 10
Final answer: x=5, y=10~
Answer:
62x^2 + 16x + 1
Step-by-step explanation:
The area of a square is Side times Side.
One of the sides is (8x + 1). So the equation is,
(8x + 1) * (8x + 1)
62x^2 + 16x + 1
Answer:
we can call a 21 sided polygon as henicosagon.
