Start by distributing the 8: 
-160=22+(8)(3p)+(8)(-4)

Now we have:
-160=22+24p-32


Combine like terms: 
-160=(24p)+(22-32)


Now we have:
-160=24p-10


Add 10 to both sides:
24p-10+10=-160+10


Now we have:
24p=-150


Divide both sides by 24: 
24p/24=-150/24

Final answer: p=-25/4

-160=22+8(3p-4)
Use distributive property
-160=22+24p-32
-160=24p-10
Add 10 for both side
-160+10=24p-10+10
-150=24p
Divided 24 for both side
-150/24=24p/24
p=-6.25
Check:
-160=22+8(3p+4)
-160=22+8[3(-6.25)-4]
-160=22+8(-18.75-4)
-160=22+8(-22.75)
-160=22-182
-160=-160. As a result, x=-6.25. Hope it help!

If x2=18x+y and y2=18y+x, then find the value of root
mezya [45]

Answer:

\sqrt{x^2+y^2+1}=18

Step-by-step explanation:

We are given:

x^2=18x+y\qquad\qquad[1]

y^2=18y+x\qquad\qquad[2]

Subtracting [1] and [2]:

x^2-y^2=18x+y-(18y+x)

Operating:

x^2-y^2=18x+y-18y-x

Recall:

x^2-y^2=(x-y)(x+y)

Substituting:

(x-y)(x+y)=18x+y-18y-x

Rearranging:

(x-y)(x+y)=18x-18y-(x-y)

(x-y)(x+y)=18(x-y)-(x-y)

Dividing by x-y (recall x≠y):

x+y=18-1=17

x+y=17\qquad[3]

Now we add [1] and [2]:

x^2+y^2=18x+y+18y+x

Rearranging:

x^2+y^2=18x+18y+x+y

x^2+y^2=18(x+y)+(x+y)

x^2+y^2=19(x+y)

Substituting from [3]

x^2+y^2=19*17=323

Adding 1:

x^2+y^2+1=324

Taking the square root:

\sqrt{x^2+y^2+1}=\sqrt{324}=18

Thus:

\mathbf{\sqrt{x^2+y^2+1}=18}
