Answer:
The standard form of the quadratic equation is x² + 3·x - 4 = 0
Step-by-step explanation:
The standard form of a quadratic equation is a·x² + b·x + c = 0
Given that the expression of the quadratic equation is (x + 4)·(x - 1) = y, we can write the given expression in standard form by expanding, and equating the result to zero as follows;
(x + 4)·(x - 1) = x² - x + 4·x - 4 = x² + 3·x - 4 = 0
The standard form of the quadratic equation is x² + 3·x - 4 = 0
The graph of the equation created with MS Excel is attached
Answer:
48
Step-by-step explanation:
2x + 3 = 15
2x = 15-3
2x = 12
x = 12 ÷ 2
x = 6
8x = 6 × 8
8x = 48
B or D, I forgot whether the open circle or the circle is the equal to one, if I had to guess I'd say B
Me either :(
but you got this giiirrrrlll
