When the smaller of two consecutive integers is added to to two times the larger, the result is 29

KengaRu [80]

Let the numbers be X and X+1. X+2(X+1)=29 X+2X+2=29 3X=29-2 X=27/3 X=9. Thus, the Numbers are therefore 9 and 9+1=10 i.e 9 & 10. Thus, when 9 is added to (2*10=20), the result is 29.

simplify the following expression: (x+7/4x) + (5/x-8) I also attached a photo of the problem if you get confused on how I typed

Gnoma [55]

Answer:

$\frac{x^{2} + 19x - 56}{4 {x}^{2} - 32x}$

Step-by-step explanation:

Start by making the denominators of both fraction the same. This can be done by multiplying one fraction's denominator by the other.

After simplifying and combining the two fractions together, check if the numerator can be factorised such that there is a common factor in the denominator and numerator. In this case, the numerator cannot be factorised.

Lastly, expand the denominator.

$\frac{x + 7}{4x} + \frac{5}{x - 8}$
