Since it is a cube, each side is the same length. Therefore, it would be:
l = (x+5)*(x+5)*(x+5)
Which is the same as
x^3 [Cubed] + 125 = L

3(x+5) each side is x+5 so times that by 3. Distribute the 3 to both the x and the 5 to get 3x+15.

Answer:

(a) $X(t)=X(0)+\Delta X*t=5-0.5*t$

(b) $X(t)=X(0)+\Delta X*t=1+0.5*t$

Step-by-step explanation:

a) For the students, they start at X(0)=5 h and ΔX=-0.5 h/week.

We can write

$X(t)=X(0)+\Delta X*t=5-0.5*t$

b) For the professors, they start at X(0)=1 h and ΔX=+0.5 h/week.

We can write

$X(t)=X(0)+\Delta X*t=1+0.5*t$

c) The seew which they will be watching the same amount of hours will be the 4th week.

$X(t)=5-0.5*t=1+0.5*t\\\\5-1=(0.5+0.5)*t\\\\t=4\, weeks$

The amount of hours will be

$x(4)=1+0.5*4=1+2=3\,hours$

In the parallelogram, find

Luda [366]

Answer:

${114}^{o}$

Step-by-step explanation:

From the question,

$< KLO = {73}^{o}$

$< MLO={41}^{o}$

Base on the properties of a parallelogram, KL //JM and JK //ML

So, we can say that, <MLO alternates with <KJO and <KLO alternates with <MJO

Since alternative angles are equal,

$< MLO= < KJO = {41}^{o}$

$< KLO= < MJO = {73}^{o}$

In addition

$< MLK= < KJM = < KLO + < MLO$

$< MLK = {41}^{o} + {73}^{o} = {114}^{o}$

Therefore, m<KJM= ${114}^{o}$
