Answer:
The answer is A. The length is 3 times the width.
Step-by-step explanation:
In the picture, it tells us that m is the width. That must mean that 3m is the length. m × 3 = 3m, so when you substitute it, it becomes width × 3 = length.

Answer:
Step-by-step explanation:
Say you have a function 
. If you wanted to find f(3), you would replace the number in the parentheses, in this case 3, with x, to get 
When combining functions, you should do the same thing.
Here, we have 
We want to find f(g(x)). So, you should replace x in the function f(x) with the function g(x). 
So, f(g(x)) would equal 
, which equals .

Answer:
A number line from negative 5 to 5 in increments of 1. An open circle is at 3 and a bold line starts at 3 and is pointing to the right.
Step-by-step explanation:
We can start by dividing the inequality by 3 to get ...
8 -4x < 2(x -5)
And we can divide by 2 to simplify further to ...
4 -2x < x -5
Now, we can add 2x+5, which gives ...
9 < 3x
and then divide by 3 again:
3 < x
This is graphed on a number line as described above.
Answer:
32m2
Step-by-step explanation:
find one triangle.
A=1/2×base×height
1/2×8×3= 12m2
1/2×8×5= 20m,2
12+20=32m2
