Answer:
The solutions are: 5 and 7

Explanation:
First we would need to put the equation in the standard form which is:
ax² + bx + c = 0
This can be done as follows:
x² - 7x + 38 = 5x + 3
x² - 7x + 38 - 5x - 3 = 0
x² - 12x + 35 = 0
By comparison:
a = 1
b = -12
c = 35


Now, to get the roots, we would need to use the quadratic formula attached in the images.
By substitution, we would find that:\
either x = \frac{12+ \sqrt{(-12)^2-4(1)(35)} }{2(1)} = 7

or x = \frac{12- \sqrt{(-12)^2-4(1)(35)} }{2(1)} = 5

Hope this helps :)

Serjik [45]

Answer:

The value of the shares Samantha owns is $3,010

Step-by-step explanation:

Step 1

We add all the shares together and find out the cost of each share per dollar

Samantha owns 70 shares, Nyla owns 50 shares, and Jerry owns 40 shares.

Total amount of shares = (70 + 50 + 40) shares

= 160 shares

Step 2

The cost of share per dollar =

Values of shares/ Total number of shares

= $6,880/160 shares

= $43

1 share = $43

Step 3

The value of the shares Samantha owns is calculated as:

Number of shares Samantha owns × cost of share per dollar

Samantha owns 70 shares

Hence:

= 70 × $43

= $3010

The value of the shares Samantha owns is $3,010
