1. Kalena was asked to prove ifx(x - 1)(x + 1) = x3 - X represents a polynomial identity. She
Verdich [7]

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

1.) 6% of 38 1% of 38 = 3.8 ( you just move the decimal placement over by one. 1% * 6 = 6% 3.8 * 6 = 6% 3.8 * 6 = 22.8 6% =22.8 2.) 5% of 90 90/5 = 5% 90/5 = 18 18 = 5% 3.) 15/5 = 9/x 15/5 = 3 3 = 9/x (nine divided by ? is three?....3!) 3 = 9/x(3) 3 = 9/3 3 = 3 x = 3 4.) 1/12 = .8/x Multiply each side by ten. 1/12 * 10 = 5/6 .8/x * 10 = 8/x 5/6 = 8/x Cross Multiply (switch the second numbers around) 5x = 6*8 Simplify 5x = 48 Divide both sides by 5 to get x by itself 5x/5 = x 48/5 = 9.6 *Whoo last problem lol* 5.) A three liter bottle costs $2.97 what is the unit rate. Well the unit is the object we're talking about, in this case a liter bottle. The unit rate is how much it costs or is per unit. Now that that's out of the way... 3L = 2.97 Like the other problems we want to get x by itself, so we'll divide by three) 3L/3 = L 2.97/3 = .99 L = .99 The Unit Rate is $0.99 per liter bottle. Hope this helped :)
