<span>9x(2+y)
multiply 9x by everything inside parenthesis:</span>

<span>9x*2 = 18x</span>

<span>9x*y = 9xy

so you have 18x +9xy</span>

<span> 2 of the equations are similar:

</span><span>18x+(9x⋅y) 
</span><span>(9x⋅2)+(9x⋅y) 1</span>

Darnelle drew this figure and the accompanying equations.
kondor19780726 [428]

Answer:

Option D. w + x = z

Step-by-step explanation:

see the attached figure to better understand the problem

we have

w+x+y=180 ----> equation A

y+z=180 ----> equation B

equate equation A and equation B

w+x+y=y+z

Subtract y both sides

w+x=z

This equation satisfy the <em><u>Triangle Exterior Angle Theorem</u></em> (An exterior angle of a triangle is equal to the sum of the opposite interior angles)

Solve 0= 2t^3-21t^2+ 40t
sukhopar [10]
0=2t^3-21^2+40t
switch sides
2t^3-21t^2+40t=0
solve factoring 
t(t-8)(2t-5)=0
using the zero factor principle
t=0&#10;
solve
t-8=0:t=8
solve
2t-5=0:t= \frac{5}{2}
t=0,t=8,t= \frac{5}{2}
Hope this helps
