Answer:
b = -80
Step-by-step explanation:
-16 = 0.2b
Divide both sides by 0.2
We have , -16/0.2 = 0.2b/0.2
Therefore, b = -80
Answer:
28 feet long together
Step-by-step explanation:
in 1 yard there is 3 feet so in 4 yards it would be 3(4) which is 12. add 12 to 16 and you get 28
Width=19
Length=17
72-4=68/2=34/2= 17 length
72-4=68+4=38/2=19 width

We effectively rewrite the equation as

In order for the LHS to be defined, we need to restrict
, or
. Now, the LHS will vanish when the numerator is 0, which happens for

This value is indeed smaller than 4, so the solution is
.
Because integrated math requires skills in trigonometry, I would highly recommend pre calc first
