Answer:

<u>Y is the midpoint of XZ, so XY = YZ</u>

  • 20x - 30 = 12x + 10
  • 20x - 12x = 10 + 30
  • 8x = 40
  • x = 5

<u>Find XZ:</u>

  • XZ = 2(XY) = 2(20*5 - 30) = 140

<u>The answer is: </u>

  • x = 5 and XZ = 140

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

<u>B is the midpoint of AC, so AB = BC</u>

  • 4x + 3 = 2x + 15
  • 4x - 2x = 15 - 3
  • 2x = 12
  • x = 6

<u>Find AC:</u>

  • AC = 2(AB) = 2(4*6 + 3) = 54

<u>The answer is:</u>

  • x = 6, AC = 54

What is the correct answer?
vesna_86 [32]

Answer:

(C) x^3+11x^2+34x+24

Step-by-step explanation:

The volume of a rectangular prism is V=lwh

x+4=L

x+1=W

x+6=H

Thus:

(x+4)(x+1)(x+6)

(x^2+5x+4)(x+6)

x^3+5x^2+4x+6x^2+30x+24

x^3+11x^2+34x+24

Therefore, the correct answer is (C) x^3+11x^2+34x+24

In trapezoid WXYZ, identify WX. PLEASE HELP!!!
matrenka [14]

Answer:

The length of WX is 31 units.(third option)

Step-by-step explanation:

Given that In trapezoid WXYZ, WX║ZY and S and T are the mid points of the sides WZ and XY. We have to find the length of WX.

By trapezoid mid-segment Property,

A mid-segment of a trapezoid join the midpoints of the two non-parallel sides of trapezoid. The length of the mid-segment is the average of the lengths of the two bases and is parallel to the bases of the trapezoid.

∴ ST=\frac{WX+ZY}{2}

⇒ 48=\frac{WX+65}{2}

⇒ 96=WX+65

⇒ WX=96-65=31

The length of WX is 31 units.(third option)
