Isabella solved the following equation: 4x – 2x + 8 = 6(x + 4) step work justification 1 4x – 2x + 8 = 6x + 24 distributive property 2 2x + 8 = 6x + 24 combine like terms 3 −4x + 8 = 24 addition property of equality 4 −4x = 16 subtraction property of equality 5 x = −4 division property of equality which step has an incorrect justification? (make sure to type only the number of the step into the blank: 1, 2, 3, 4 or 5)

Step 2 is incorrect.

Step-by-step explanation:

step 2

Step-by-step explanation:

Step 2 is incorrect because Isabella is  not combining like terms but doing Subtraction between two like terms that were already on the same side of the equality.

what is the approximate angle of acb if abc is 25cm and the length of segment bc is 15

step-by-step explanation:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
