Answer:
Percentage increase = 269%
Step-by-step explanation:
Price of a DVD last week = $2.87
Price of the same DVD this week = $10.59
Increase in the price of DVD between last week and this week = 10.59 - 2.87
= $7.72
Therefore, percentage increase in the price of DVD = 
= 
= 268.99
= 269%
Answer:
The correct option is commutative property.
Step-by-step explanation:
The expression that Renee is simplifying is:
It is provided that, Renee recognizes that 7 and 
are reciprocals, so she would like to find their product before she multiplies by 
.
The associative property of multiplication states that:
The commutative property of multiplication states that:
The distributive property of multiplication states that:
The identity property of multiplication states that:
So, Renee should use the commutative property of multiplication to find the product of 7 and ,
Thus, the correct option is commutative property.
Answer: 0, 1, -3
Step-by-step explanation:
f(x) = x^3 +2x^2 -3x
f(x) = x(x^2 +2x-3)
f(x) = x(x-1)(x+3)
to find zeroes, plug into f(x) and solve for each value of x. doing this gives 0, 1, and -3

To find the height of the TV you first need to realize that the question is giving you dimensions for a triangle.
Every triangle has a hypotenuse and two sides. To find the hypotenuse you square both sides, add them, and then square root. So to find one of the sides you get the hypotenuse, square it, and subtract the square length of the given side.
The equation is 25^2-20^2.
Which if simplified is 625-400, the then solution is going to be 225.
You next will square root 225, 225^(1/2). Which your answer should be 15 inches for the missing side length.
