Answer:

4 m squared minus 20 m n + 25 n squared; a perfect square trinomial

Step-by-step explanation:

Given expression,

(negative 2 m + 5 n) squared

By using (a+b)² = a² + 2ab + b²,

∵ A trinomial which is the square of a binomial is called a perfect square trinomial.

Thus,  is a perfect square trinomial.

Answer:

House A

Step-by-step explanation

For house A:

divide 125,260 by to to find 10%.

10% = 12,526.The you divide this by two to get 5%.

5% = 6,263.Next add the original figure with the 5%. To makes things simpler insted of adding 5% percent twice(since were calculating for two years) just add the 10% to the original figure you get:

125,260 + 12,526= $137,786

For house B:

This is a little different than before. Find ten percent then 5 percent.

10%= 12,016

5%=6,008.Next to find 1% divide the 10% again!

1%-1,201.6,After add the five percent and 1% to find 6%.

6%=7,209.6. Multiply the 6% by 2 to find the price for 2 years.Next add the original number to the 12%.

12%=14,419.2

17,419.2+120,160= $134,579.2

In conclusion:

Compare the prices-

A=$137,786

B=$134,579.2

House A earns more money after two years.

valentinak56 [21]

Answer:

<h3>Q cuts the diagonal PA into 2 equal halves, since the diagonals of rhombus meet at right angles.</h3><h3>The value of x is 8.</h3>

Step-by-step explanation:

Given that Quadrilateral CAMP below is a rhombus. the length PQ is (x+2) units, and the length of QA is (3x-14) units

From the given Q is the middle point, which cut the diagonal PA into 2 equal halves.

By the definition of rhombus, diagonals meet at right angles.

Implies that PQ = QA

x+2 = 3x - 14

x-3x=-14-2

-2x=-16

2x = 16

dividing by 2 on both sides, we will get,

x =\frac{16}{2}

<h3>∴ x=8</h3><h3>Since Q cuts the diagonal PA into 2 equal halves, since the diagonals of rhombus meet at right angles we can equate x+2 = 3x-14 to find the value of x.</h3>

The line segment \overrightarrow{PA}=\overrightarrow{PQ}+\overrightarrow{QA}

\overrightarrow{PA}=x+2+3x-14

=4x-12

=4(8)-12 ( since x=8)

=32-12

=20

<h3>∴ \overrightarrow{PA}=20 units</h3>
