You want total number made in 4 m onths, so adding all numbers is correct, but it is per 1 month, so multiply by 2
A because you need brain for most problems
D works
pick A and D
F(x)·g(x) = (3x-2)(5x) = 15x^2 -10x
solution
1) <span>Expand
</span><span>9x−6−12x
2) </span><span>Gather like terms
</span><span>(9x−12x)−6
3) </span> <span>Simplify
</span><span><span>−3x−6</span></span>
Formula: A = pi(r)^2
1/4(2)^2pi
1/4 * 4 pi = just pi
The area would be 3.14
2x+4=10
2x=6
x=3
2(3)+4= 10
(plus, on parallelograms like that, parallel sides are equal to each other)
