Answer:
7t^5 - t^3
6x -3 +2x/y
Step-by-step explanation:
A. (7t^8 - t^6)/t^3
Separate into 2 fractions
(7t^8/t^3) - (t^6)/t^3
Remember a^b / a^c = a^ (b-c)
7 t^(8-3) - t^(6-3)
7t^5 - t^3
B (12x^2y - 6xy +4x^2)/2xy
Separate into 3 fractions
12x^2y/2xy - 6xy/2xy +4x^2/2xy
Remember a^b / a^c = a^ (b-c)
12/2 x^(2-1) y^(1-1) - 6/2 x/x * y/y +4/2 x^(2-1) /y
6 x y^0 -3*1*1 +2 x/y
Remember that x^0 = 1
6x -3 +2x/y
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
Answer:
Right, isosceles
Step-by-step explanation:
The triangle contains one right angle and two legs of the same length. This fufills the requirements fro both a right and isosceles triangle.
