Remember the sides of a square are all equal legnth
4 sides

pereimiter=4s where s is the legnth of a side

so
P=4(4x-2y)
P=16x-8y

the periimiter is 16x-8y

Oh gosh, I'm confused myself..
But wouldn't it be (4x - 2y) x 4 ?Because lets pretend (4x-2y) equaled 5. 
so you would do 5+5+5+5 (5x4) because there are 4 sides on a square!
Am i right? xD

Find the product of the complex numbers (-5+ 8i) and (3 - 8i)
Liula [17]

Answer: 49+64i

Step-by-step explanation:

Concept to know:

i=√-1

i²=-1

i³=-i

i^{4}=1

-------------------------------------

 (-5+8i)(3-8i)

=-15+40i+24i-64i²

=-15+64i-64i²

=-15+64i+64  (remember, i²=-1)

=49+64i

Hope this helps!! :)

Please let me know if you have any question or need further explanation

Can someone please tell me the answer on this.

Answer: x = 31

Step-By-Step:

<u>To Find x:</u>

<u />\left(2x+20\right)+\left(x+10\right)+\left(2x-5\right)=180 (Angle Sum Property Of Triangles)

(Remove the brackets)

<u />2x+20+x+10+2x-5=18<u />

(Group Accordingly)

<u />2x+x+2x+20+10-5=180<u />

= 5x+20+10-5=180

= 5x\:+\:25 =180

= 5x= 180 - 25

= 5x = 155

= x=\frac{155}{5}

= 31

<u>Therefore</u> x = 31

So,

Angle A = x + 10 = 31 + 10 = 41

Angle B = 2*x + 20 = 2*31 + 20 = 82

Angle C = 2*x - 5 = 62 - 5 = 57
