Answer:
1/4
Step-by-step explanation:
3+9=12
12/3=4
The surface area will be 4 times the original size. Here is why: You are doubling each dimension, and area is a 2 dimensional measurement. Because of this whatever you are doing to the length of the side will happen 2 times. In this case it would be x2 x2 which equals 4. You can provide evident by using a cube. The surface area of a cube with side lengths of 1 would be 1 x 6=6 square inches. If you double the side length, it would be 4 x 6= 24 square inches.
Answer:
y= 5x - 47
Step-by-step explanation:
I assume you're asking how to make it into an equation form?
If yes then...
m=5 , pt (8, -7)
y= 5x +b
sub pt (8, -7) to find b
-7 = 5(8) + b
-7 = 40 + b
-7 - 40 = b
-47 = b
therefore, y= 5x - 47
Creo que la respuesta es c
