Answer:
What's a Solution to a System of Linear Equations? Note: If you have a system of equations that contains two equations with the same two unknown variables, then the solution to that system is the ordered pair that makes both equations true at the same time.
Step-by-step explanation:
Answer
x - 1 + 6x^2
Step-by-step explanation:
Write al the sides together: 2x + 5 + x^2 - 6 + 4x^2 + 2x + x^2 - 3x
Then organize the terms: 2x + 2x - 3x + 5 - 6 + x^2 + x^2 + 4x^2
Simplify: 2x + 2x - 3x + 5 - 6 + x^2 + x^2 + 4x^2
2x + 2x -3x = 4x - 3x = 1x or x
x + 5 - 6 + x^2 + x^2 + 4x^2
5 - 6 = -1
x - 1 + x^2 + x^2 + 4x^2
x^2 + x^2 + 4x^2 = 2x^2 + 4x^2 = 6x^2
x - 1 + 6x^2
Answer:
86 m²
Step-by-step explanation:
It can be convenient to think of the figure as an 8×12 rectangle with a 4×5 triangle cut off the corner.
The rectangle area is the product of its length and width:
(12 m)×(8 m) = 96 m²
The triangle area is half the product of its base and height:
(1/2)(4 m)(5 m) = 10 m²
Then the area of the figure is the difference of these:
96 m² -10 m² = 86 m²
