28/42 ÷2
14/21 ÷2
2/3
28/42 in simplest form is = 2/3
F(x) = x² - 3x
g(x) = √x - 1
f(g(x))= (√x - 1)² - 3(√x - 1) = (√x - 1)(√x - 1 - 3) =(√x - 1)(√x - 4) =
= √x √x -1*√x -4*√x +4 = x -5√x +4
Answer: x -5√x +4
<u>Let's take this problem step-by-step</u>:
<u>Let's take the case of the tennis ball first</u>:
⇒ the diameter of the balls are 2.7inches
⇒ therefore they are spheres with diameters of 2.7 inches
⇒ <em>for an x-ray</em> <u>they are circles with a diameter of 2.7in</u>
<u>Now for the cylinder container</u>:
⇒ It has a width of 2.7inches
⇒ Its height:
⇒ is three balls stacked together
⇒ Height is 3 * 2.7in = 5.4 inches
⇒ <u>Overall dimension: A rectangle that is 2.7 in x 8.1 in</u>
<u />
<u />
<u>Answer:</u>
- <u>A circle with a diameter of 2.7 in</u>
- <u>A rectangle that is 2.7 in x 8.1 in</u>
<u></u>
Hope that helps!

Answer:
l=20m
w=5m
Step-by-step explanation:
Let "l" be the length of the rectangle &
let "w" be the width of the rectangle
l=15+w
P=2(l+w)
50m=2(15m+w+w)
50m=2(15+2w)
50m=30m+4w
20m=4w
w=5m
l=15m+w
l=15m+5m
l=20m
Proof:
P=2(l+w)
P=2(15m+w+w)
50m=2(20m+5m)
50m=40m+10m
50m=50m
