The graph below shows the temperature in Paula's house over time after her mother turned
on the air conditioner. Describe the relationship
between the two quantities.

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.

2y+y=5

add 2y and y

the first is 13 the second is 1 the third is 8 and the fourth is 7
