ANSWER

A. Noah is correct because the two sides of the equation are equivalent expressions.

EXPLANATION

The equation given to Noah was

-3(x + 4) + 2x = 2(x - 6) - 3x

He expanded to get:

-3x - 12 + 2x = 2x - 12 - 3x

He then further simplified each side of the equation to get;

-x - 12 = -x - 12

Both sides of this equation are equivalent.

Therefore the equation has infinitely many solutions.

The correct answer is A

Answer:

Option A) Noah is correct because the two sides of the equation are equivalent expressions.

Step-by-step explanation:

We are given the following information in the question:

-3(x + 4) + 2x = 2(x - 6) - 3x\\-3x - 12 + 2x = 2x - 12 - 3x\\-x - 12 = -x - 12

The above equation has infinitely many solutions.

Infinite solution:

If an equation end up with equal values on each side of the equation, then there are infinite solution as for all the values of x the equations would be satisfied.

Noah is correct.

Option A) Noah is correct because the two sides of the equation are equivalent expressions.

Snezhnost [94]

Answer:

D. ∠B = ∠B' = 74° and ∠C = ∠C' = 66°

Step-by-step explanation:

Given,

\angle A=3x-8\\\angle B=5x-6\\\angle C=4x+2

We know,sum of all 3 angles of a triangle is 180°

Doing so ,

\angle A+\angle B+\angle C=180\\3x-8+5x-6+4x+2=180

Simplifying all like terms,

12x-12=180\\12x-12+12=180+12\\12x=192

Dividing both side by 12

x=\frac{192}{12}

x=16

Now we plug this in each angles and find their exact values.

\angle A=3x-8=(3\times16)-8=48-8=40°

\angle B=5x-6=(5\times16)-6=80-6 =74°

\angle C=4x+2 = (4\times16)+2=64+2=66°

Now substituting the x=16 in angles of dilated triangle.

\angle A'=(2\times16)+8=32+8= 40°

\angle B'=90-16=74°

\angle C'=(5\times16)-14=80-14=66°

We see that all the corresponding angles are equal and as far as the options are concerned only option (D) matches.
