Answer:

x = 19

Step-by-step explanation:

Assuming all angle measures are in degrees, the sum of them is 180:

(3x +16) +(4x -15) +(2x +8) = 180

9x +9 = 180 . . . . collect terms

x + 1 = 20 . . . . . . divide by 9

x = 19 . . . . . . . . . .subtract 1

The value of x is 19.

I need help with three and four

mart [117]

Answer:

3: $a^{2}+2ab+b^{2}$

4: $8x^{3} -12x^{2}+6x-1$

Step-by-step explanation:

Question 3 can be re-written as:

$(a+b)(a+b)$

which equals:

$a^{2}+2ab+b^{2}$

Question 4 can be re-written as:

$(2x-1)(2x-1)(2x-1)$

Doing the first 2 brackets gives us:

$(4x^{2} -4x+1)(2x-1)$

Expanding these two:

$8x^{3} -4x^{2} -8x^{2} +4x+2x-1$

Simplifying it:

$8x^{3} -12x^{2}+6x-1$
