The given equation is
4x + 8x² = 88
That is,
8x² + 4x - 88 = 0
or
2x² + x - 22 = 0
The x-axis intercepts are determined by the solution of the quadratic equation as
x = (1/4) [-1 +/- √(1+176)] = 3.076 or -3.376
Answer: 3.076 or -3.376
50+8
50 represents tens place value, while 8 represents the ones place value.
75 extra minutes because $61.20-$49.95=$11.25 and $11.25/$0.15=75.
$180 is the cost of the goal, and $15 is the cost of each soccer ball.
