Suppose you're given the formula r = s + 2t. if you know that s is three times greater than t, how could you rewrite the formula?
a. r = 3(s + t)
b. r = 5t
c. r = 3(s + 2t)
d. r = 5s

B .    R = 5t

Step-by-step explanation:

From the question above; given that R = S + 2t

If s is three times greater than t, it simply means s = 3t

so, we can easily substitute s= 3t in the initial equation.

Replacing or substituting s = 3t in the  equation: R = S + 2t, the equation becomes;

R =  3t  +  2t

R = 5t

Therefore we could re-write the formula as R = 5t

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
