Answer: C=2*3.14*r
Step-by-step explanation:
You just plug in 3.14 for pi, it's pretty simple
3/2x-7=-11
We move all terms to the left:
3/2x-7-(-11)=0
Domain of the equation: 2x!=0
x!=0/2
x!=0
x∈R
We add all the numbers together, and all the variables
3/2x+4=0
We multiply all the terms by the denominator
4*2x+3=0
Wy multiply elements
8x+3=0
We move all terms containing x to the left, all other terms to the right
8x=-3
x=-3/8
x=-3/8
Answer: 6 x (18-9) = 54
Step-by-step explanation: 18-9 is 9 and 6 times 9 is 54
