Marcel made an error when he used the distributive property to solve the problem shown. which sentence describes the error?

In Step 2, 90 should be multiplied by the quantity 10 – 12, not by 10.

Step-by-step explanation:

Consider the provided expression.

when x=10

Solve the above expression as shown:

Step 1:

Step 2: Substitute x=10.

Step 3: Open the parenthesis.

Step 4: Simplify

From the above calculation we can say that the error is:

In Step 2, 90 should be multiplied by the quantity 10 – 12, not by 10.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
