Answer:
Step-by-step explanation:
Remark
The measurement of the arc is 3Pi
that represents 108 / 360 of the circle.
Equation
108/350 2 * pi * R = 3* pi
Solution
Pi is on both sides of the equation. They both cancel.
108/360 = 0.3
0.3 * 2 * R = 3
0.6 * R = 3
R = 3/0.6
R = 5
15=2x
There are fifteen 1 blocks and two x blocks, which makes 15=2x(or 2x=15)
solution
given a=1_9k and b=j+k
Now,ab=(1_9k)(j+k)
=1((j+k)-9k(j+k)
=j+k_9jk-9k^2
=k_9k^2+j_9jk
=k((1_9k)+j(1_9k)
=(1_9k)(k+k)
3p*3p*3p*3p*3p*3p
Multiply exponents
3p^6
expand
3p*3p*3p*3p*3p*3p = 3p^6
