3x + 2y - 2x + y + 12 —> x + 3y + 12
4y + 3y + 3x - 6y - 10 -2 —> 3x + y - 12
12 - 3y - 2x + x + 2x —> x - 3y + 12
x + 3y + 2x - 3x + 7 + 5 —> 3y + 12
That's how I would graph it...
Area of each wall is 10*8 = 80 square feet
there are 5 walls so total wall area is 5*80=400
he needs two coats on each wall so he needs to cover 2*400=800 square feet
so he needs to buy 3 galon containers
Answer:
(x - 7)(x + 3) = 0
Step-by-step explanation:
To factorise the quadratic
Consider the factors of the constant term (- 21) which sum to give the coefficient of the x- term (- 4)
The factors are - 7 and + 3, since
- 7 × 3 = - 21 and - 7 + 3 = - 4, thus
(x - 7)(x + 3) = 0 ← in factored form
