o b. $20 down with equal payments of $10 for 12 weeks
o c. $5 down with equal payments of $10 for 15 weeks
o d. $0 down with equal payments of $15 for 9 weeks

first one: $10 + $5 * 24 = 130 dollar

second: $20 + $10 * 12 = 140 dollar

third: $5 + $10 * 15 = 155 dollar

fourth: $0 + $15 * 9 = 135 dollar

Step-by-step explanation:

idk

step-by-step explanation:

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.
