Complete Question:
Emily and Zach have two different polynomials to multiply: Polynomial product A: (4x2 – 4x)(x2 – 4) Polynomial product B: (x2 + x – 2)(4x2 – 8x) They are trying to determine if the products of the two polynomials are the same. But they disagree about how to solve this problem.
Answer:
Step-by-step explanation:
<em>See comment for complete question</em>
Given
Required
Determine how they can show if the products are the same or not
To do this, we simply factorize each polynomial
For, Polynomial A: We have:
Factor out 4x
Apply difference of two squares on x^2 - 4
For, Polynomial B: We have:
Expand x^2 + x - 2
Factorize:
Factor out x + 2
Factor out 4x
Rearrange
The simplified expressions are:
and
Hence, both polynomials are equal
Answer: The axis of symmetry is x = 0
This is basically saying that the axis of symmetry is the vertical y axis
The vertex is either the highest point or the lowest point on the parabola, depending on what the value of 'a' is. If the vertex is the y intercept, then the vertex is on the y axis. The axis of symmetry goes through the vertex.

Answer:
whatever the number of crocodiles is ___ multiply by 2 then add 4
____ x 2 = ____+4 =___
number of crocodiles____×2=___+4=__
( multiply symbol is x )
example : 5 crocodiles x 2 = 10 crocodiles + 4 = 14 turtles
Answer:
e ≥ 2w
Step-by-step explanation:
To make this easier, let us consider the case of Eliza being exactly twice as old as wendy
that would mean that twice the age of Wendy is the age of Eliza
e = 2w
but since she is AT LEAST twice as old as her, the age of eliza can be greater than twice of wendy and it might be equal to twice the age of Wendy
Hence, the symbol '=' will be replaced by '≥'
Hence, the correct relation is
e ≥ 2w
