<h2>Answer:</h2>

Hence, the value of (f+g)(x) is:

                 5x^2+3x+1

<h2>Step-by-step explanation:</h2>

We are given a function f(x) in terms of variable x as:

f(x)=3x^2+4x

and function g(x) in terms of variable x as:

g(x)=2x^2-x+1

Now we are asked to find the value of (f+g)(x)

We know that:

(f+g)(x)=f(x)+g(x)

Hence, on putting the value of both the functions:

(f+g)(x)=3x^2+4x+2x^2-x+1

on combining like terms we get:

(f+g)(x)=3x^2+2x^2+4x-x+1

(f+g)(x)=5x^2+3x+1

                  The answer is:

                       5x^2+3x+1

Find the sum of the coefficients in the expansion of (x+1)^12
MariettaO [177]

Answer:

<h2>2¹²</h2>

Step-by-step explanation:

The sum of the coefficients in the expansion of (x+1)^12:

= 12C0 + 12C1 + 12C2 + . . . + 12C11 + 12C12

the formula says that this sum equal to 2¹².

Other examples

The sum of the coefficients in the expansion of (x+1)^3:

3C0+3C1+3C2+3C3

=8 = 2³

The sum of the coefficients in the expansion of (x+1)^4:

4C0+4C1+4C2+4C3+4C4

=16 = 2⁴

Kevin and Randy Muise have a jar containing 70 coins, all of which are either quarters or nickels. The total value of the coins
Nikitich [7]

Answer:

50 nickels, 20 quarters.

Step-by-step explanation:

System of equations (q = # of quarters, n = # of nickels):

<em>q + n = 70, 0.25q + 0.05n = 7.50</em>

the first equation can be changed to q = 70 - n, so we are able to <em>substitute q with 70 - n</em>.

So, it will look like <em>0.25*70 - 0.25n + 0.05n = 7.50</em>. This can be simplified to <em>0.2n = 10</em>, which means that n = 50.

Knowing that we can solve <em>q + 50 = 70</em>, which means that q = 20.
