Answer: factorise the equation 49x^2+70x+25
Step-by-step explanation:
49x^2+70x+25
(7x)^2+2*7x*5+(5)^2
(7x+5)(7x+5)
therefore the sides of the square are (7x+5)(7x+5)
Answer:
C = 6.28
A = 3.14
Step-by-step explanation:
use the equations for area and circumference to solve
C = pi d
A = pi r^2
I like to remember these using the saying Cherry pie's delicious, Apple pie's are too so Cherry = pi's delicious, Apple = pi's r 2
so with the diameter of 2 plug in to get circumference
C = 3.14 (2)
C = 6.28
and the equation for area uses radius not diameter but we know that d/2=r so radius is 1, plug in to solve
A = 3.14 (1)^2
A = 3.14 (1)
A = 3.14
Hope this helps! :)
Answer:
Each class should get 17 tickets. 4 tickets will be left over.
