Answer:
16
Step-by-step explanation:
f(x) = 2x² when x>4
We cannot use this expression of f to calculate f(4)
because ,this expression define f for the value of x
that are greater (not equal) than 4.
………………………………………………………
f(x) = 4x when x ≤ 4 , here x is can be equal to 4
(notice the sign ≤ )
Therefore
f(4) = 4 × (4) = 16
Your answer is going to be 228
<u><em>Answer:</em></u>
79.8 (Guessing)
<u><em>Step-by-step explanation:</em></u>
for the side walls, split 19 in half, and get 9.5.
9.5 + 9.5 = 19
19 + 19 + 29.2 + 12.6
(2 walls) + (bottom floor) + (height/y)
79.8
There are 48 green ribbons
<h3><u>Solution:</u></h3>
Given that the ratio of red ribbons to green ribbons is 4 to 6
Which can be written in following way:-

There are total number of 32 red ribbons
We have to determine the number of green ribbon
Let the number of green ribbon be ‘6a’
And number of red ribbons be "4a"
Given number of red ribbons = 32
4a = 32
a = 8
number of green ribbon = 6a = 6(8) = 48
Therefore number of green ribbons is 48
