Solve for x in the picture below.

netineya [11]

Ok so there's 5 sides

let's find interior angle sum

formula is S=180(n-2)

n in this case is 5 since there are 5 sides

S=180(5-2)
S=180(3)
S=540

so now add the 5 angle lengths up to 540

5x+2+10x-3+7x-11+13x-31+8x-19=540
43x+-62=540
+62 +62
43x=602
divide both sides by 43
x=14!!!!!

WILL MARK BRAINLIEST, PLEASE DON'T DO THOSE OFFSITE LINKS I KNOW BETTER THAN TO CLICK EM

Alexus [3.1K]

Answer:

A p

Step-by-step explanation:

We have

$12x {}^{ - 3} y {}^{ - 1}$

Remeber that

$x {}^{ - n} = \frac{1}{x {}^{n} }$

$12 \frac{1}{x {}^{3} } \frac{1}{y {}^{1} }$

Now, plug in

So now we plug in -1 for x and 5 for y

$12 \frac{1}{ { - 1}^{3} } \frac{1}{5 {}^{1} }$

Simplify

$- \frac{12}{5}$

A is the answer.

What is the sum of the polynomials?

Vaselesa [24]

Answer:

<u>The answer is the option B</u>

$4m-24n+3$

Step-by-step explanation:

we have

$17m-12n-1+4-13m-12n$

Group terms that contain the same variable

$(17m-13m)+(-12n-12n)+(-1+4)$

Combine like terms

$(4m)+(-24n)+(3)$

$4m-24n+3$

Answer:

Step-by-step explanation:

$5x^2-2x+16=4x^2+6x\qquad\text{subtract}\ 4x^2\ \text{from both sides}\\\\x^2-2x+16=6x\qquad\text{subtract}\ 6x\ \text{from both sides}\\\\x^2-8x+16=0\\\\\text{Put the values of}\ x\ \text{to the equation and check the equality:}\\\\A.\ x=-6\\\\(-6)^2-8(-6)+16=36+48+16=100\neq0\\\\B.\ x=6\\\\6^2-8(6)+16=36-48+16=4\neq0\\\\C.\ x=-3\\\\(-3)^2-8(-3)+16=9+24+16=49\neq0\\\\D.\ x=-4\\\\(-4)^2-8(-4)+16=16+32+16=64\neq0\\\\E.\ x=4\\\\4^2-8(4)+16=16-32+16=0\\\\F.\ x=18\\\\18^2-8(16)+16=324-128+16=212\neq0$
