Someone , i have to show work too :

Step-by-step explanation:

At most, the area is 140 ---> the area is (3x + 2)10

So, as an inequality, you get (3x + 2) 10 ≤ 140

Simplify

30x + 20 ≤ 140

30x ≤ 120

x ≤ 4

Can 3x + 2 be 15?

Plug in the greatest value of x, and get 3*4 + 2, which is 12 + 2, which is 14

No, at most the length can be 14, which is less than 15.

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
