Answer:
25 ft
Step-by-step explanation:
The diagram shows two triangles that are similar. Similar triangles have equal angles and sides that are proportional to each other. Since the base of each triangle is given, we can find the proportion of the sides:

Given the ratio of the smaller to larger triangle, we can set up a proportion to find the missing height of the larger triangle:
, where 'x' represent the height of the tree
cross-multiply: x = (5)(5) or 25 ft
Answer:
i think the values for a and b are: a=2 and b=1/4
The answer to this equation is x= -19/3
Answer:

Step-by-step explanation:
Let the numbers be 
Such that:

Make z the subject

For their product to be maximum, we have:

Substitute
in 

Open bracket

Differentiate w.r.t x and y


Since the products are maximum, then 
For 

Factorize:

Split

Make y the subject

For 

---------------------------------------------------
Substitute y = 0


Factorize



---------------------------------------------------
Substitute 



Re-arrange


Factor x out

Divide through by x



Recall that: 


Take LCM
