You are given that all three sides are equal. You also know that all three angles are also equal. Therefore since all three angles are equal and every triangle has 180 degrees, each angle is 180/3 = 60

So

7x - 3 = 60                     Add three to both sides

7x - 3 + 3 = 60 + 3        Combine

7x = 63                          Divide by 7

7x/7 = 63/7

x = 9                              And that's your answer.

SVEN [57.7K]

Answer:   <em>She earned $72 per day. </em>

<em>The computation that will give Samantha's daily pay is:  \frac{\$3960}{5\times 11}</em>

Step-by-step explanation:

Samantha did not work on weekends. That means, <u>she worked for 5 days in a week</u>.

Given that, she worked at the insurance company for 11 weeks. So, <u>the total number of her working days</u> =(5\times 11)= 55

She earned a total of $3,960.

So, the amount she earned daily =\frac{\$3960}{55}=\$72

Ryan planted flowers in a rectangular garden. The width of the garden is left parenthesis x minus 5 right parenthesis(x−5) feet
Nookie1986 [14]

。☆✼★ ━━━━━━━━━━━━━━  ☾  ━━━━━━━━━━━━━━ ★✼☆。

- The equation :

Area = length x width

- Substitute the values in :

Area = (x - 5)(x - 5 + 22)

(Note : the 'x' is for the algebraic expression x in the example above)

- Now you have to simplify the second parenthesis:

Area = (x - 5)(x + 17)

- Now expand :

Area = x^2 + 17x - 5x - 85

- Simplify by collecting like terms :

Area = x^2 + 12x - 85

(Note : x^2 means x squared)

Now you have your answer as:

x^2 + 12x - 85 feet^2

Using arithmetic operations, rewrite this polynomial in standard, simplest form.
dangina [55]
(3x2 + 9x + 6) − (8x2 + 3x − 10) + (2x + 4)(3x − 7)

First distribute the (2x+4)(3x-7) to get 6x2-2x-28
After this just add the like terms for all parts of the expression.
(3x2-8x2+6x2)+(9x-3x-2x)+(6+10-28)
x2+4x-12

So you answer is x2+4x-12
