Equation #1:

Equation #2:

-4 is smaller than 13, so the solution to equation #1 is smaller than the solution to equation #2.
The answer is a.
Well in this cause you could use the area, For a rectangle it’s LxW.Which means that if the width was 4cm and the length is 6cm you would times 6cm by 4cm,and the answer is 24cm2 so if you needed an answer there ya go
Let the height of the first tower be x, then the second tower is (160 - x) m taller than the first tower. Then
tan 30 = (160 - x)/80
160 - x = 80 tan 30
x = 160 - 80 tan 30 = 160 - 46.19 = 113.8 m
Therefore, the height of the first tower is 113.8 m.
2x +3x = 180
5x = 180
x = 36
-8bits is equivalent yo 1 byte
-bit is(0 or 1)
So each pixel requires 3 bytes
Primary colors are RGB(red,green and blue),so each color represent one byte.
The frame size is:
1280×1024=1310720 pixels
So that the frame contained 1310720 pixels
The size of the frame buffer is equal to the product of RGB and frame pixels:
=3 × 1310720
=3932160 bytes
