Answer:
D)x = 4∕3y – 4
Step-by-step explanation:
![\frac{x}{4} + \frac{y}{3} = 1](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B4%7D%20%20%2B%20%20%5Cfrac%7By%7D%7B3%7D%20%20%3D%201)
![3x + 4y = 12](https://tex.z-dn.net/?f=3x%20%2B%204y%20%3D%2012)
![3x = 12 - 4y](https://tex.z-dn.net/?f=3x%20%3D%2012%20-%204y)
![x = 4 - \frac{4}{3} y](https://tex.z-dn.net/?f=x%20%3D%204%20-%20%20%5Cfrac%7B4%7D%7B3%7D%20y)
![x = 4 - \frac{4}{3} y](https://tex.z-dn.net/?f=x%20%3D%204%20-%20%20%5Cfrac%7B4%7D%7B3%7D%20y)
It is B.Scale factor=New length/old length=8/2=4
Answer:
Option C (72)
Step-by-step explanation:
In the figure attached we can see a rectangle ABCD with length 12 cm and width 9 cm.
A triangle PEF with height BE and base EF.
Since side AE = 3 cm, so side EB = EC = 9 - 3 = 6cm
and EF = AD = 12 cm
Now we will find the area of of the parts of the card that are not shaded.
Area of parts that are not shaded = Area of rectangle - area of shaded triangle
= (12×9) -
= 108 -
Option c) 72 cm² is the area of non shaded part.

Answer:
26
Step-by-step explanation:
18 - 2^4 * (-0.5)
Calculate 2 to the power of 4 and get 16.
18−16(−0.5)
Multiply 16 and −0.5 to get −8.
18−(−8)
The opposite of −8 is 8.
18+8
Add 18 and 8 to get 26.
