II. Identify the terms and write the factors in the following expressions: ATTACH AN ANSWER PAPER TO IT IF CORRECT YOULL GET A CROWN
1. x2– 5
2. 7a2b2+ 3abc
3. -4p2q
4. –mn + 2n2– 3m2

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.
