A= π(r)^2 so it would be A= π(7x7) and so A= π(49). Hope it helps :-)
Answer: 83,662,774
Step-by-step explanation:
I might be wrong but I think the answer would be -x+2x+6 as a simplified version because if you use the equation (x+4•x+3)-3x(x+1)=a (or any letter you choose), you will get 3x+x^2+12+4x-3x-3x^2=y. Then, you can combine like terms:
4x-2x+12=a
Answer:
Tom got 20 words correct and 30 definitions correct
Step-by-step explanation:
2m-4 = x+nx switch sides
