positive 35
Step-by-step explanation:
x2 + 3(x + y) given
4(2) + 3(4+5) problem

615.44 because area of a circle=pi×radius^2
You can write every speed as the ratio between the space and time, so in this case you have
Remark
Answer: The second one. The second step removes the brackets on the right. It uses the <em><u>distributive property</u></em> which puts back the common factor that was taken out of the two terms 6x and 24. Quite often the distributive property is useful when presenting a problem to be solved.
