Answer:
See below
Step-by-step explanation:
The first one 'cubes' the denominator AND the numerator:
(-2/5)^3 = -2/5 * -2/5 * -2/5 = -8/125
The second one 'cubes' only the denominator:
-2/5^3 = -2 / (5 * 5 * 5) = - 2 / 125
Answer:
To “associate” means to connect or join with something and The associative property states that you can add or multiply regardless of how the numbers are grouped. ... In other words, if you are adding or multiplying it does not matter where you put the parenthesis.

Answer:
14 months
Step-by-step explanation:
60x+60=50x+200
10x+60=200
10x=140
x=14
60(14)+60=900
50(14)+200=900
Answer:
P = 42.84 cm
Step-by-step explanation:
A half-circle is joined to an equilateral triangle with side lengths of 12 units.
We need to find the perimeter of the resulting shape.
The perimeter of the half cirle is πr.
The diameter of the circle is 12. It means radius is 6 units.
An equilateral triangle has 3 equal sides. So, perimeter of the triangle is given by :
P = πr + 12 +12
= 3.14(6) + 24
= 42.84 cm
Hence, the perimeter of the resulting shape is 42.84 cm.
