Factorise e2 + 4e
pls me xoxox

Step-by-step explanation:

Here,

e²+4e

If we take e common we will get,

=e. e+ 4e

= e(e+4)

Which is your final result but you cannot equate it to zero because it is not mentioned in the question. But I think the question is incomplete.

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.
