To evaluate this expression, we simply plug the value of the variable into the expression and solve.
Since m = -4, plug a -4 in for m every time the m appears in the expression.
So we have (-4)^2 + 6(-4) + 3.
Start by simplifying the exponent.
(-4)^2 is 16.
Now multiply.
A positive times a negative is a negative.
So 6(-4) is -24.
So we have 16 + 24 + 3 which is 43.

Now,
Also, the second derivative is calculate by:
Answer:
My opinion:
I'll say 70 percent, bc we do learn English or whatever language you're learning all along to communicate, yes a big factor in our lives, basic math helps with logic and solving problems irl but advanced math helps with a career that has to do with math. same with science and history but I believe as long as you know general knowledge you will do fine
c = number of children
s = number of students
a = number of adults
since the theater has a capacity of 189, then c + s + a = 189.
there are half as many "a" as "c", so then a = c/2 or 2a = c.
so the cost for all children since the price for one is 5 bucks, the total will be 5*c or 5c.
likewise, the total cost for students is 7*s or 7s.
and for adults likewise is 12*a or 12a.
we know all ticket sales was 1372, so then 5c + 7s + 12a = 1372.
now, let's use the elimination method on that system of equations of two variables, let's multiply hmmmm say the first equation by -7, to eliminate the "s".
