Remember:
The product of the sum of two perfect cubes:
a³ + b³ = (a + b)(a² - ab + b²)
The product of the difference of two perfect cubes:
a³ - b³ = (a - b)(a² + ab + b²)
----------------------------------------------------------------------------------------------------------------
Remember to follow PEMDAS.
(5c)(5c) = 25c²
(5c)(-2/3) = -10c/3
(2/3)(5c) = 10c/3
(2/3)(-2/3) = -4/9
25c²- 10c/3 + 10c/3 - 4/9
Combine like terms
25c² (-10c/3 + 10c/3) - 4/9
25c² - 4/9
25c² - 4/9 is your answer
hope this helps
B. This is clear because of using the intercepts method. You know it crosses at y = 3 and x = -7. You also know to shade over by testing a spot in the shaded area.
Answer:
$44,313.75
Step-by-step explanation:
First, we need to turn the km into meters. There are 1000 meters in a km meaning we need to multiply each of these values by 1000.
0.101 km * 1000= 101 meters
0.065 km * 1000 = 65 meters
Now we need to multiply these values together to find the area of the field
101m * 65m = 6,565
Finally, we need to multiply this area by the cost per square meter
6,565 / 6.75 = $44,313.75
The total repair will cost $44,313.75
