Perfect square trinomial. For example, take the binomial (x + 2) and multiply it by itself (x + 2). The result is a perfect square trinomial.

Answer:

Check whether the first and last terms of the trinomial are perfect squares.

Multiply the roots of the first and third terms together.

Compare to the middle terms with the result in step two

If the first and last terms are perfect squares, and the middle term’s coefficient is twice the product of the square roots of the first and last terms

in 1st figure

2:1=(x+2):2

2/1=(x+2)/2

4=x+2

x=2.

Similarly in the 2nd figure

8:5=(8+3):(5+x)

8/5 = 11/ (5+x)

8(5+x) =55

40+8x=55

8x=15

x=15/8

x=1.875

18 divide by 2 * 3/5-2 simplify show all work
liraira [26]

Answer:

9

Step-by-step explanation:

I would guess it looks like this - if not then tell me

\frac{18}{ \frac{2 \times 3}{5 - 2} }

2×3=6

5-2=3

Then there's only

\frac{18}{ \frac{6}{3} }

Which is equal to

\frac{18}{1}  \times  \frac{3}{6}  =  \frac{54}{6}  =  \frac{9}{1}  = 9

A trader old a writ watch for h.3150 after giving a 10% dicount.Find the marked price of the watch
vivado [14]

The marked price of the wrist watch after the trader sold a wrist watch for $3150 after giving a 10% discount is $3500.

First, let us understand the percentage:

A percentage is a fraction of a whole expressed as a number between 0 and 100. Nothing is zero percent, everything is 100 percent, half of everything is fifty percent, and nothing is zero percent.

To determine a percentage, we need to divide the portion of the whole by the whole itself and multiply by 100.

Let the marked price be x.

So,

According to the question;

x - x * 10% = 3150

x - x * 10/100 = 3150

100x - 10x / 100 = 3150

90x = 3150 * 100

x = 3150 * 100 / 90

x = 3500

So, the marked price is $3500.

Thus, the marked price of the wrist watch after the trader sold a wrist watch for $3150 after giving a 10% discount is $3500.
