Answer:
C. Kalena made a mistake in Step 3. The justification should state: -x²
+ x²
Step-by-step explanation:
Given the function x(x - 1)(x + 1) = x3 - X
To justify kelena proof
We will need to show if the two equations are equal.
Starting from the RHS with function x³-x
First we will factor out the common factor which is 'x' to have;
x(x²-1)
Factorising x²-1 using the difference of two square will give;
x(x+1)(x-1)
Note that for two real number a and b, the expansion of a²-b² using difference vof two square will give;
a²-b² = (a+b)(a-b) hence;
Factorising x²-1 using the difference of two square will give;
x(x+1)(x-1)
Factorising x(x+1) gives x²+x, therefore
x(x+1)(x-1) = (x²+x)(x-1)
(x²+x)(x-1) = x³-x²+x²-x
The function x³-x²+x²-x gotten shows that kelena made a mistake in step 3, the justification should be -x²+x² not -x-x²

Answer:
The perimeter is 127.1 cm
Step-by-step explanation:
30+25+25=80
(2)(3.14)(15)=94.2
94.2/2=47.1
Divide by two because of the semicircle
80+47.1=127.1
Answer:
A. (2,-0.5)
Step-by-step explanation:
A pair of coordinates is always (x,y) so
If you insert the numbers into the equation you get
10(-0.5) = 3(2) - 11
-5 = 6 - 11
-5 = -5
Therefore (2,-0.5) is the point that likes on the graph
