The given inequality is

First we need to remove the inequality, and on doing so we will get two inequalities, which are

Adding 1 to both equations

Dividing both sides by 7

So the required solution is
![(- \infty ,-3/7] U ( 5/7, \infty)](https://tex.z-dn.net/?f=%20%28-%20%5Cinfty%20%2C-3%2F7%5D%20U%20%28%205%2F7%2C%20%5Cinfty%29%20)
Step-by-step explanation:
area of the triangle
1/2xbxh
1/2(12x9)
1/2(108)
area of triangle is 54in²
area of rectangle
2(L+W)
2(15+6)
2(21)
area of rectangle is 42in²
Total area is 96in²
Answer:

Step-by-step explanation:
First find the slope using the slope using the given points. Remember that the slope is the change in y over the change in x.

So now we have the equation
, and we need to find out what b is. We can do this by pointing a point (either one, but I'll use -1,2) into the equation

Rearrange the equation so it equals b

Put it together and that's the final equation!

Answer:
surface area of the cube is 96m² and the volume is 64m³
Step-by-step explanation:
Surface area of the cube = 6x²
x is the side length
Given
x = 4metres
Surface area of the cube = 6(4)²
Surface area of the cube = 6(16)
Surface area of the cube = 96m²
Volume of the cube = x³
Volume of the cube = 4³
Volume of the cube = 64m³
Hence the surface area of the cube is 96m² and the volume is 64m³
