Answer:
5/6
Step-by-step explanation:
72 minutes
We require their hourly rate of work
Maria cleans
the house in 1 hour
Sasha cleans
of the house in 1 hour
let x be the time it takes both to clean the house
+
= 
multiply through by 6x
3x + 2x = 6
5x = 6 ⇒ x = 
Together they can clean the house in 72 minutes

Answer:
72
Step-by-step explanation:
SA Formula = 2(L x W) + 2(L x H) + 2(W x H)
2(6x2) + 2(6x3) + 2(2x3)
2(12) + 2(18) + 2(6)
24 + 36 + 12
The answer would be 72 ft sqaured
The expression 4a^2c^2 - (a^2-b^2+c^2)^2 has to be factored.
4a^2c^2 - (a^2 - b^2 + c^2)^2
=> (2ac)^2 - (a^2 - b^2 + c^2)^2
=> (2ac - a^2 + b^2 - c^2)(2ac + a^2 - b^2 + c^2)
=> (b^2 - (a^2 - 2ac + c^2))((a^2 + 2ac + c^2) - b^2)
=> (b^2 - (a - c)^2)((a + c)^2 - b^2)
=> (b - a + c)(b + a - c)(a + b + c)(a - b + c)
<span>
The factorized form of 4a^2c^2 - (a^2-b^2+c^2)^2 is (b - a + c)(b + a - c)(a + b + c)(a - b + c)</span>
