For this case we have to define root properties:
![\sqrt [n] {a ^ n} = a ^ {\frac {n} {n}} = a](https://tex.z-dn.net/?f=%5Csqrt%20%5Bn%5D%20%7Ba%20%5E%20n%7D%20%3D%20a%20%5E%20%7B%5Cfrac%20%7Bn%7D%20%7Bn%7D%7D%20%3D%20a)
In addition, we know that:
On the other hand:
Thus, we can rewrite the given expression as:
ANswer:
Option B
Answer:
20x + 17 = 77 --> Addition Property of Equality:
You are adding (Addition Property) 4x to both sides of the equal sign (Equality).
20x = 60 --> Subtraction Property of Equality:
You subtracted (Subtraction Property) 17 from both sides of the equal sign (Equality).
x = 3 --> Division Property of Equality:
You divided (Division Property) 20 from both sides of the equal sign (Equality) to completely isolate the variable x.

Answer:
$960
Step-by-step explanation:
1/5= .2
1-0.2= 0.8
1200×0.8= 960
Answer:
B: 54 square feet
Step-by-step explanation:
There are 3 feet in 1 yard. The scale model is 6 square yards.
Multiply 6 by 3 to get the amount of square yards.
There are 18 square yards in the actual playground.
Since there are 3 feet in a yard, multiply 18 by 3.
This gives you your answer:
54 square feet
Answer:4x^2+22x-12
Step-by-step explanation:
height=(2x+12)
base=(4x-2)
Area of =(base x height)/2
Area of =((4x-2)(2x+12))/2
Area of =(8x^2+48x-4x-24)/2
Area of =(8x^2+44x-24)/2
Area of =4x^2+22x-12
