What is the equation of m and n???

m=47° n=52°

Step-by-step explanation:

38°,43°,m and n are all on the same line therefore they are all supplementary angles, or equal to 180°. 43° and m are also commplmentary angles or equal to 90°. This information will help with my work above.

1,3,4

Step-by-step explanation:

Given expression

3x(x-12x)+3x^2-2(x-2)^2

To solve the expression the whole square if x-2 will be evaluated first:

=3x(x-12x)+3x^2-2(x^2-4x+4)

Then, solving the brackets:

=3x(-11x)+3x^2-2x^2+8x-8

= -33x^2+3x^2-  2x^2+8x-8

= -32x^2+8x-8

Now lets look at the options one by one:

1. The term –2(x – 2)2 is simplified by first squaring the expression x – 2.

Statement 1 is true as the square will be solved first.

2. The simplified product is a binomial.

Statement 2 is false as the resulting expression is trinomial.

3. After multiplying, the like terms are combined by adding and subtracting.

Statement 3 is correct as the like terms with same variables are added.

4. The parentheses are eliminated through multiplication.

Statement 4 is correct. The brackets are solved by multiplying the integers into the brackets.

5. The final simplified product is –28x2 +8x – 8.

Statement 5 is false as the result is = -32x^2+8x-8  ..
