Answer:
Area = 3x^2 + 4x
Step-by-step explanation:
Givens
W = x
L = 3x + 4
Formula
Area = L * W
Solution
Area = x(3x + 4)
Area = 3x^2 + 4x
For this case we have that by definition, the line equation of the slope-intersection form is given by:
![y = mx + b](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20b)
Where:
m: It's the slope
b: It is the cut-off point with the y axis
According to the statement we have:
![m = \frac {1} {2}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%20%7B1%7D%20%7B2%7D)
Thus, the equation is of the form:
![y = \frac {1} {2} x + b](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%20%7B1%7D%20%7B2%7D%20x%20%2B%20b)
We substitute the given point and find "b":
![-4 = \frac {1} {2} (1) + b\\-4 = \frac {1} {2} + b\\-4- \frac {1} {2} = b\\b = - \frac {9} {2}](https://tex.z-dn.net/?f=-4%20%3D%20%5Cfrac%20%7B1%7D%20%7B2%7D%20%281%29%20%2B%20b%5C%5C-4%20%3D%20%5Cfrac%20%7B1%7D%20%7B2%7D%20%2B%20b%5C%5C-4-%20%5Cfrac%20%7B1%7D%20%7B2%7D%20%3D%20b%5C%5Cb%20%3D%20-%20%5Cfrac%20%7B9%7D%20%7B2%7D)
Finally, the equation is of the form:
![y = \frac {1} {2} x- \frac {9} {2}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%20%7B1%7D%20%7B2%7D%20x-%20%5Cfrac%20%7B9%7D%20%7B2%7D)
Answer:
![y = \frac {1} {2} x- \frac {9} {2}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%20%7B1%7D%20%7B2%7D%20x-%20%5Cfrac%20%7B9%7D%20%7B2%7D)
Answer:
= 8sqrt2
Step-by-step explanation:
Area of a trapezium is given by the formula;
1/2(a+b)h
;
Where a and b are the parallel sides and h is the perpendicular height.
a = 3 cm, b= 5 cm
To get; h, we use the Pythagoras theorem;
h² = 3² - 1²
h² = 8
h = √8
= √4√2
= 2√2
Thus;
Area = 1/2(3 +5) 2√2
= 1/2 ×8 × 2√2
<u> = 8√2 cm² or 8sqrt2 cm²</u>
