Need fast do not understand this one. solve: (x+5) / (x+8)=1+(6) / (x+1) showing all work.

Step-by-step explanation:

Given the equation , you need to make the addtition indicated on the right side of the equation:

Now, multiply both sides of the equation by (x+8) and (x+1):

Now, apply Distributive property:

Simplifying, you get:

Subtract 5 and 15x from both sides:

Finally, divide both sidesby -9:

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
