As the sides shown are same so the base of large triangle is double the base of smaller triangle

so,

2(2x-8)=20

distributing 2 over bracket,

4x-16=20

adding 16 to the other side

4x=20+16

4x=36

dividing by 4 on the right side

x=9

AB = 3 + x
ICE Princess25 [194]

The given quadrilateral ABCD is a parallelogram since the opposite sides are of same length AB and DC is 4 and AD and BC is 2.

<u>Step-by-step explanation</u>:

ABCD is a quadrilateral with their opposite sides are congruent (equal).

The both pairs of opposite sides are given as AB = 3 + x , DC = 4x , AD = y + 1 , BC = 2y.

  • AB and DC are opposite sides and have same measure of length.
  • AD and BC are opposite sides and have same measure of length.

<u>To find the length of AB and DC :</u>

AB = DC

3 + x = 4x

Keep x terms on one side and constant on other side.

3 = 4x - x

3 = 3x

x = 1

Substiute x=1 in AB and DC,

AB = 3+1 = 4

DC = 4(1) = 4

<u>To find the length of AD and BC :</u>

AD = BC

y + 1 = 2y

Keep y terms on one side and constant on other side.

2y-y = 1

y = 1

Substiute y=1 in AD and BC,

AD = 1+1 = 2

BC = 2(1) = 2

Therefore, the opposite sides are of same length AB and DC is 4 and AD and BC is 2. The given quadrilateral ABCD is a parallelogram.

11w times 6x

240w times 18y

you always use the last numbers and that would equal...

____________________________________________________________

66x times 4320y=

285120 divide it by 6= 47520

then by 12

47520 divided by 12=

3960-80= 3880

3880 divided by 16 times 4

your answer is 970y
