They are the same because the first one you do 2 x 3 which equals 6 and then you do 2 x 6 which equals to 12. Then you do 12 x 6 which equal to 72. Then for the second one you do parentheses first so that 2x6 which equals 12 and then you x 6 so now it would be 12 x 6 equal to 72. SO YOUR ANSWER IS THEY ARE THE SAME
The value of the constant k when the value of x and y is 7 and 3 respectively in the equation xy=k is 21.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The value of the constant k when the value of x and y is 7 and 3 respectively in the equation xy=k can be written as,
Hence, the value of the constant k when the value of x and y is 7 and 3 respectively in the equation xy=k is 21.

Set s(t) = 0 which means it hits the ground. The formula doesn't fit the parameters given as it shows that the pitcher is standing on something 37 feet high.
<span>s(t)=-16t^2+140t+37 and has an initial velocity of 140.
Graphing or solving this, t= 9 seconds when it hits the ground.
The velocity V(t) is the derivative of s(t)
V(t) = -32t+140
V(9) = -148 ft/second which is going down

I am not sure what the question is but maybe the answer is ...
2.5 < d
Hope I helped :-)
The answer is 1
