Answer:

U  ={ Parallelograms}

A= { Parallelogram with four congruent sides}={ Rhombus,Square}

B ={ Parallelograms with four congruent angles} ={ Rectangle, Square}

So, AB= { Square}

So among all the parallelograms "Square" is the only parallelogram which has all congruent sides as well as all congruent angles.

The square of a positive number is equal to its triple added to 28. What is this number?​

\huge{ \rm{Answer:}}

The roots of the equation are 7 and -4, because 7 - 4 = 3 and 7. - 4 = -28

Step-by-step explanation:

The positive number is equal to 7.

Assuming that the number is equal to "x" we have:

\begin{gathered}x^2 = 3x + 28\\\\x^2 - 3x - 28 = 0\\\\a = 1\\\\b = -3\\\\c = -28\\\end{gathered}

By the sum and product method, we have:

\begin{gathered}S = -b / a\\\\S = -(-3) / 1\\\\S = 3\\\\\end{gathered}

\begin{gathered}P= c / a\\\\P = 28 / 1\\\\P = 28\\\\\end{gathered}

Please help me with this one.​
borishaifa [10]

Answer:

  • V = 16
  • W = 48

Step-by-step explanation:

The triangles are congruent when corresponding sides are congruent.

__

ΔFGH ≅ ΔABC means corresponding sides are ...

  (GH, BC) = (V, 16)

  (HF, CA) = (48, W)

Corresponding sides being congruent means ...

  V = 16

  W = 48

Find the 7th term of a geometric sequence with t1 = 6 and r = 4.
Helen [10]

To solve for the 7th term of a geometric sequence with t1 = 6 and r = 4, we use the following equation:

<span>
a(n) = a(1) r^(n-1)
a7 = (6) 4^(7-1)
a7 = 24576</span>

Hope this answers the question. Have a nice day. Feel free to ask more questions.

Write out how you found the answer.
ollegr [7]

Step-by-step explanation:

DC = DF + FE + EC = 3 + 14 +6 = 23 in (\because FE = AB)

Area of trapezoid ABCD

=  \frac{1}{2} (AB + CD) \times BE \\  \\  = \frac{1}{2} (14 + 23) \times 8 \\  \\  = 37 \times 4 \\  \\  = 148 \:  {in}^{2}
