252.95=(18+b)×9.35
what is b

b=9.053

step by step explanation:

b=9.0534759358

Step-by-step explanation:

first you have to divide both sides by 9.35

you get

27.0534759358

then you subtract 18 from it

you get

9.0534759358

so b=9.0534759358

also what kind of math teacher would give you this problem

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.

the answer is c

hope this !
