Answer: Length = 642 cm
Concept:
Here, we need to know the idea of how to find the area of a rectangle.
Area (rectangle) = l × w
l = length
w = width
Solve:
<u>Given information</u>
A = 24396 cm²
w = 38 cm
<u>Given expression</u>
A = l × w
<u>Substitute values into the expression</u>
24396 = l × (38)
<u>Divide both sides by 38</u>
24396 / 38 = l × 38 / 38
Hope this helps!! :)

Answer:
? = 1 (assuming right-angled triangle)
Step-by-step explanation:
This is an application of Pythagoras' Theorem, but rearranged:
is, of course, 10, so 10 - 9 = 1, and
.
Answer:
f(x) = 3x - 1
Step-by-step explanation:
The line can be represented in the form f(x) = mx + b, where m is the rate of change of the line and b is the value of the function when x = 0.
Looking at the graph, we can tell that when x = 0 the function = -1. (The point on the line and the y-axis).
We can also tell that when x increases by 1, y increases by 3. The points (0,-1) and (1, 2) are both on the line and their difference in x is 1 and their difference in y is 3.
The formula for slope (rate of change) is , so m =
or 3.
Now we have the equation for the line is f(x) = 3x - 1
