Answer:
4 miles
Step-by-step explanation:
the data we have is:
Miles Minutes
6 ⇒ 90
and the thing we want to know is how many miles she could walk in 60 minutes:
Miles Minutes
6 ⇒ 90
x ⇒ 60
where the x represents the unknown number of miles she will walk in 60 minutes.
we solve this problem using rule of three, for this we multiply cross quantities (6 by 60) and then we must divide by 90:
x = 6*60/90
x = 360/90
x = 4
in 60 minutes she walks 4 miles.
Reflection along x-axis is just a swapping of left and right sides. It does not change the size or area of the hexagon.
Hence, the correct option is B.
B. (a - b)(a + b)
C. a^2(b-b^2)
D. a^2b^2(b - a)
The factor of the expression into an equivalent form a²b - (ab)² would be; C
Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions.
To derive equivalent expressions of some expressions, we can either make it look more complex or simple. Usually, we simplify it.
We need to factor the expression into an equivalent form a²b - (ab)²
This expression could also be given by;
a²b - (ab)²
Now, we know that:
a²- b² = (a + b) (a - b)
Now plug the values then we get;
Hence, the factor of the expression into an equivalent form a²b - (ab)² would be; C
