Answer: Question 1 is x=9
Question 2 is y=-3
Step-by-step explanation:
Answer:
A. -41/15.
Step-by-step explanation:
15x^2 + 23x - 41 = 0
Product of the roots of ax^2 + bx + c = c/a.
Thus the product of the roots of this equation = -41/15.
Answer:
$452,340
Step-by-step explanation:
Fencing (perimeter):
255+255=450+450+450= 1860 feet
1860 / 3 = 620 yards
620 x $27 = $16,740
Seed (area):
Square area: a = lw
a = 450 x 450
a = 202500 feet
202500 x $2 = $405,000
Triangle area: a = 1/2bh
a = 1/2 x 255 x 120
a = 1/2 x 30600
a = 15300
15300 x $2 = $30,600
Add the cost of the fencing and seeds up.
$16,740 + $405,000 + $30,600 = $452,340
