PLEASE HELP! 25 PTS!!
zubka84 [21]

Answer:

Solution given:

f(x)=\frac{x-16}{x^2+6x-40}

g(x)=\frac{1}{x+10}

now

f(x)+g(x)=\frac{x-16}{x^2+6x-40}+\frac{1}{x+10}....(1)

now

factoring x²+6x-40

we get

x²+10x-4x-40

x(x+10)-4(x+10)

(x+10)(x-4)

now substituting in equation 1 ,we get

f(x)+g(x)=\frac{x-16}{(x+10)(x-4)}+\frac{1}{x+10}

taking l.c.m

=\frac{(x-16)+(x-4)}{(x-10)(x-4)}

=now

opening bracket

\frac{x-16+x-4}{x²-10x-4x+40}

=\frac{2x-20}{x²+6x-40}

So

answer is :

B. \bold b\frac{2x-20}{x^2+6x-40}

What number must you add to complete the square? x^2 + 24x = 17
kenny6666 [7]

Complete the square: x^2 + 24x = 17

Identify the coefficient of x. It is 24. Take half of that coefficient: 24/2 = 12.

Now add the square of 12 to both sides of x^2 + 24x = 17

x^2 + 24x + 144 = 17 + 144

Write in factored form:

(x + 12)^2 = 161

Taking the square root of both sides:

x+12 = plus or minus
