Gianna is substituting t = 2 and t = 7 to determine if the two expressions are equivalent. 5 (2 t + 3) 5 t + 25 Which statement is true? Both expressions are equivalent to 35 when t = 2. Both expressions are equivalent to 85 when t = 7. Both expressions are equivalent to 60 when t = 7. The expressions are equivalent.

Both expressions are equivalent to 35 when t = 2

Step-by-step explanation:

Given

Expression 1: 5(2 t + 3)

Expression 2: 5t + 25

When t = 2

5 (2 t + 3)

= 5(2*2 + 3)

= 5(4 + 3)

= 5(7)

= 35

5t + 25

= 5*2 + 25

= 10 + 25

= 35

When t = 7

5(2 t + 3)

= 5(2*7 + 3)

= 5(14 + 3)

= 5(17)

= 85

5t + 25

= 5*7 + 25

= 35 + 25

= 60

Both expressions are equivalent to 35 when t = 2

Area=legnth times width
perimiter=legnth+legnth+width+width
perimiter=2(legnth+width)

so
304=p=2(legnth+width
5520=area=legnth times width

so we have
304=2(l+w) and
5520=lw

304=2(l+w)
divide by 2 to simplify
152=l+w
subtract w
152-w=l

subsitute 152-w for l

5520=lw
5520=(152-w)(w)
distribute
5520=152w-w^2
subtract 152w from both sides
5520-152w=-w^2
add w^2 to both sides
w^2-152w+5520=0
factor the left side
(w-60)(w-92)=0
set each to zero
w-60=0
w=60
w-92=0
w=92
w=92 or 60

dimentions are
60 yd by 92 yd
