First option is the correct option.

Step-by-step explanation:

Factor out X from the expression

Using , factor the expression

Write all numerators above the Least Common Denominators x ( x - 3 ) ( x + 3 )

Multiply the parentheses

When there is a (-) in front of an expression in parentheses, change the sign of each term in the expression

Distribute -x through the parentheses

Using , simplify the product

Collect like terms

Subtract the numbers

Distribute x through the parentheses

Write 7x as a sum

Factor out X from the expression

Factor out 2 from the expression

Factor out x + 5 from the expression

Hope this helps...

Best regards!!

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
