Answer:

Step-by-step explanation:

x^2+6x+5x = x^2 + 11x = x*(x+11)

But I do not know what you are looking for? Zeroes? Then they are x=0 and x= -11

The coordinates of the vertices of a polygon are (−5, 1) , (−1, 3) , (2, 3) , (2, −2) , and (−3, −1) .

Using the distance formula $d=\sqrt{(x_2-x_1) +(y_2-y_1) }$ Then we assign the points letter for simplicity

$A= (-5.1),B=(-1,3),C=(2,3),D=(2,-2),E=(-3,-1)$ . The distance formula gives us the magnitude between two points hence,

$AB=\sqrt{(-5-(-1))^2+ (-1-3)^2}=\sqrt{16+16}= 5.65$

$BC=\sqrt{(-1-2)^2+(3-3)^2}= \sqrt{9}=3$

$CD=\sqrt{(2-2)^2+((3-(-2))^2} =\sqrt{25}=5$

$DE=\sqrt{(2-(-3))^2+(-2-(-1))^2} =\sqrt{26+1} =5.099$

$AE=\sqrt{(-3-(-5))^2+(-1-1)^2}= \sqrt{4+4} =\sqrt{8}=2.82$

$Perimeter= AB+BC+CD+DE+AE\\Perimeter=5.65+3+5+5.099+2.82=21.57 units$

Solve for x in the equation:<br> 3 over 7 x + 5 = 8 <br> — please help i will give brainliest!

Eddi Din [679]

Answer:

3/7 x +5=8

move 5 to the other side

3/7 x= 8-5

3/7 x= 3

then move 7 to the other side it's sign is ÷ it will be ×

then 3x=3×7

3x=21

then move 3to the other side it's sign is × it will become ÷

x= 21/3

x= 7
