Answer:

(2x - 1)

Step-by-step explanation:

  • <em>Volume of a rectangular prism is: V = lwh, where l= lenght, w= width, h= height</em>
<h3>Given</h3>
  • V = 36x³ + 60x² + x - 20
  • l = (3x + 4)
  • w = (6x + 5)

and

  • h = ?
<h3>Solution</h3>

Since the volume is the polynomial of third degree and the two of the factors are of the first degree, the third factor is going to be a first degree  as well in the format of (mx +n)

<u>So we have below equation:</u>

  • 36x³ + 60x² + x - 20 = (3x + 4)(6x + 5) (mx + n)

<u>We can work out the value of m and n:</u>

  • 3x*6x*mx = 36x³
  • 18mx³ = 36 x³
  • m = 2

<u>And</u>

  • 4*5*n = -20
  • 20n = -20
  • n = -1

So we get the factor of (mx + n) = (2x - 1)

<u>Therefore </u>

  • h = (2x - 1)

<u>Proof of the polynimial is correct:</u>

  • (3x + 4)(6x +5)(2x - 1) =
  • (18x²+39x+20)(2x - 1) =
  • 36x³ - 18x² + 78x² - 39x + 40x - 20 =
  • 36x² + 60x² + x - 20

State the angle relationship and state the measure of each angle indicated that makes lines u and v parallel
notka56 [123]

Answer:

5) Alternate Exterior angles       90º

6) Same side Interior angles.     132º if that says 48º on the page

7) Corresponding angles.       too blurry but they are congruent

8) Alternating Exterior angles.       too blurry but they are congruent

Step-by-step explanation:

Congruent means they are the same measurement just as a reminder :).

I need help I will give you 10 points
KIM [24]

Answer:

k = - 2

Step-by-step explanation:

Lines g(x) and f(x) passes through the points (2, 0), (0, 2) & (4, 0), (0, 4)

Since both the lines are parallel, so slopes of lines g(x) and f(x) would be same.

Therefore,

Slope of line g = Slope of line f = (2-0)/(0 - 2) = 2/-2 = - 1

Equation of line g(x)

For point (0, 2)

y- intercept (b) = 2

y = mx + b

g(x) = - 1x + 2 [y = g(x)]

g(x) = - x + 2

Equation of line f(x)

For point (0, 4)

y- intercept (b) = 4

y = mx + b

f(x) = - 1x + 4 [y = g(x)]

f(x) = - x + 4

It is given that:

g(x) = f(x) + k

g(x) - f(x) = k

(-x + 2) - (-x + 4) = k

-x + 2 + x - 4 = k

2 - 4 = k

-2 = k

k = - 2
