What is the answer too n+ 2 = -14-n ?
Irina18 [472]

Answer:

n = -8

Step-by-step explanation:

n + 2 = -14 - n

+n              + n                Add n to both sides

2n + 2 = -14

     - 2     - 2                   Subtract 2 from both sides

2n = -16                          Divide both sides by 2

n = -8

sveticcg [70]

Answer:

(3x^3 - 4y^3) ( 3x^3 + 4y^3)

Step-by-step explanation:

9x^6 – 16 y^6

Rewriting as

(3x^3) ^2 - ( 4y^3) ^2

This is the difference of squares a^2 - b^2 = (a-b)(a+b)

(3x^3 - 4y^3) ( 3x^3 + 4y^3)

X=70, y=55

The triangle is an isosceles triangles. In an isosceles triangle, the base angles are congruent.

Then use the triangle angle sum theorem and set the equation to 180.

55+55+x=180
110+x=180
x=70

The angle with 55 degrees and the angle with the variable y are alternate angles. Meaning they are congruent.
