What are the perfect square trinomials?

Answers

A perfect square trinomial is

(square of one term) + (square of another term) + (double the product of the two terms)

Let's look at the following trinomial.

X² - 14x + 49

(x - 7) (x - 7)

(x - 7)²

This trinomial would be classified as a perfect square trinomial because it factors as two identical binomials which is (x - 7)². This means that any trinomial that factors as two identical binomials is called a perfect square trinomial.

A salesperson is paid a base salary of $300 a week plus a 5% commission on the sales he generates. Which inequality best represents s, the amount of sales in dollars he must generate to earn at least $500 for the week?

Answers

The expression can be written as the inequality:

300+0.05s≥500

300$ is made per week, so we start off with

300

He also makes 5% or 0.05 from his sales, so we add in the expression 0.05x (where s is equal to his sales volume for the week)

300+0.05s

If he wants to make at least 500$ weekly, then the total of the base salary plus the commission has to be 'greater than or equal to 500.

300+0.05s≥500

Lets solve for s now...

300+0.05s≥500
subtract 300 from both sides
0.05s≥200
Divide both sides by 0.05
s≥4000

You can buy 2 songs on I-Tunes for $ 2.58, or 3 songs for $ 3.87. Write an equation to show the relationship between the number of songs, s, and the total cost, c.

Answers

Answer:

for the first pack, 1 Itune song would be 1.29 and for the other pack, for one Itune song would be 1.29 also, the relationship between these problem is that they are the same price for 1 song. The total cost for 1 is $1.29 hope this helps, have a great day! ツ

Revolutions are the turns of a wheel.
Plug in your numbers.  D=3.14*20*1
D=62.8 inches

What is the length of the hypotenuse, x, if (12, 35, x) is a Pythagorean triple?

Answers

Answer:

x = 37

Step-by-step explanation:

Lets take  12 as base (b) and 35 as perpendicular (p)

The hypotenuse (h) = x = ?

We know by using Pythagoras theorem

h^(2) =p^(2) +b^(2)

h^(2) =35^(2) +12 ^(2)

h^(2) = 1225 + 144\nh^(2)= 1369

h =√(1369)

Therefore h = 37
