Answer: For the first it would be 6, 3, and 7, 6 is double 3, and 7 is 1 more than 6, 6+3=9, and 9+7=16.
The second one is there were only 6 days that students were absent as 12 divided by 2 is 6.
A ruler because it gies you the exact measurement in inches, or centimeters and you can always multiply to find out how many feet something is.
Q1. The answer is 19.
<span>f(x)=2x+8
</span><span>g(x)=5
(f + g)(x) = f(x) + g(x)
(f + g)(3) = f(3) + g(x)
f(3) = 2 * 3 + 8 = 6 + 8 = 14
g(3) = 5
</span>(f + g)(3) = f(3) + g(x) = 14 + 5 = 19
Q2. The answer is -22.
<span>f(x)= -2x+8
g(x)=5x
</span>
(f o g)(x) = f(g(x))
(f o g)(3) = f(g(3))
g(3) = 5 * 3 = 15
(f o g)(3) = f(g(3)) = f(15) = -2 * 15 + 8 = -30 + 8 = -22
Given that, one side of the garden be 10 feet long.
So, length : l = 10 feet.
And the other side will be 5 less than three times the first side.
So, width = 3l - 5
= 3(10) - 5 Since l: length = 10
= 30 - 5
= 25
So, area = Length * width
= 10 * 25
= 250.
So, the area of Mark's garden is 250 square feet.
Hope this helps you!
