4(b + 5) = 3b + 35. what is b​

b = 15

Step-by-step explanation:

4(b + 5) = 3b + 35

Distribute:

4(b + 5)

4(b) = 4b

4(5) = 20

4b + 20 = 3b + 35

Combine like terms:

4b - 3b = 35 - 20

b = 15

Step-by-step explanation:

4(b+5)=3b+35 perform multiplication on left side

4b+4(5)=3b+35

4b+20=3b+35 Subtract 20 from each side

4b=3b+15. subtract 3b from each side

b=15

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.

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
