Question

Kadesha is simplifying the expression below. Negative (x minus 3) minus 2 (x minus 1) She lists the steps that she uses to simplify the expression as follows: Step 1: Distribute –1 through (x minus 3), and distribute –2 through (x minus 1). Step 2: Rewrite the expression as Negative x minus 3 minus 2 x minus 2. Step 3: Combine –x and –2x, and combine –3 and –2. Step 4: The simplified expression is Negative 3 x minus 5.

Answer 1

Answer:

Kadesha's steps 2,3 and 4 are wrong

Therefore the corrected 3steps are

Step 2:  Rewrite the expression as -x+3-2x+2

Step3 : Combining like terms -x-2x+3+2

Step 4: The simplified expression is -3x+5

Step-by-step explanation:

Given that Kadesha is simplifying the expression below. Negative (x minus 3) minus 2 (x minus 1)

Her steps are given below

Step 1: Distribute –1 through (x minus 3), and distribute –2 through (x minus 1). Step 2: Rewrite the expression as Negative x minus 3 minus 2 x minus 2. Step 3: Combine –x and –2x, and combine –3 and –2. Step 4: The simplified expression is Negative 3 x minus 5.

Given expression can be written as -(x-3)-2(x-1)

Now solving the expression :

-(x-3)-2(x-1)

Step 1 : Using distributive property to the given expression

Step 2: Rewrite the expression as -x+3-2x+2

Step3 : Combining like terms -x-2x+3+2

Step 4: The simplified expression is -3x+5

Kadesha's steps 2,3 and 4 are wrong

Therefore the corrected 3steps are

Step 2: we get -x+3-2x+2

Step3 : Combining like terms -x-2x+3+2

Step 4: The simplified expression is -3x+5

Answer 2

Answer:

B. She made the first error in Step 2 because Step 2 should be Negative x + 3 minus 2 x + 2.
