PLEASE HELP ME QUICK what is the simplified form of x+9/x+1 + x-2/5?
Ira Lisetskai [31]

Answer:

A

Step-by-step explanation:

C and D are both wrong for the same reason. The denominator should be (x +1)*5 which means that either A or B is correct.

C and D have an error seldom seen on Brainly. It means that the denominator has been added rather than multiplied but even the addition is a little strange. Frankly, I don't know what has to be done to get either of them.

So the answer is

numerator: 5*(x + 9) +  (x + 1)(x - 2)

denominator: 5*(x + 1)

Simplify the numerator. Remove the brackets.

numerator: 5x + 45 + x^2 - 2x + x - 2               Gather like terms

numerator: x^2 + 5x - 2x + x + 43                      Simplify

numerator: x^2 + 4x + 43

Answer

x^2 + 4x + 43

==========

5(x + 1)

5x - 10 + 65 = 90 what is the value of x?
ki77a [65]

Answer:

x =7

Step-by-step explanation:

Solve for x:

5 x - 10 + 65 = 90

Add like terms. 65 - 10 = 55:

5 x + 55 = 90

Subtract 55 from both sides:

5 x + (55 - 55) = 90 - 55

55 - 55 = 0:

5 x = 90 - 55

90 - 55 = 35:

5 x = 35

Divide both sides of 5 x = 35 by 5:

(5 x)/5 = 35/5

5/5 = 1:

x = 35/5

The gcd of 35 and 5 is 5, so 35/5 = (5×7)/(5×1) = 5/5×7 = 7:

Answer:  x = 7
