If m(x) = x2 + 3 and n(x) = 5x + 9, which expression is equivalent to (mn)(x)? 5x3 + 9x2 + 15x + 27 25x2 + 90x + 84 x2 + 5x + 12 5x2 + 24

The product of two function is

Option A

Step-by-step explanation:

We are given two function. and

Equivalent fraction:  

Using Binomial Product property

Binomial Product: (a+b)(c+d)=ac+ad+bc+bd

Hence, The product of two function is

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
