What is the solution to the following system of equations?
y = x2 + 10x + 11
y = x2 + x − 7
1 answer:
Equation 1) y = x² + 10x + 11 Equation 2) y = x² + x - 7 Subtract equations from one another. 9x = 18 Divide both sides by 9. x = 2 Plug in 2 for x in the first equation. y = x² + 10x + 11 y = 2² + 10(2) + 11 Simplify. y = 4 + 20 + 11 y = 35 Plug in 35 for y and 2 for x in the first equation to check your work. y = x² + 10x + 11 35 = 2² + 10(2) + 11 35 = 4 + 20 + 11 35 = 24 + 11 35 = 35 So, we know that our answer is correct! :))x = 2, y = 35

For this case, what we must do is find the surface area of the cube.
By definition, the surface area of a cube is given by:
Where,
L: length of the sides of the cube.
Substituting values we have:
