Answer:
This would be a $150 increase
Step-by-step explanation:
In order to find the increase in price, we need to determine the overall costs for buying and selling. In order to do that, multiply the number of shares by the cost per share.
12 * $27 = $324
12 * $39.50 = $474
Now to find the difference, we subtract the old amount from the new amount.
$474 - $324 = $150
You can use F.O.I.L. for this, which if you don't know stands for first outer inner last, so multiply the first in each parentheses, then the outer, then the inner, then the last. yours would be 3*5+3*√7+(-√7)*5+(-√7)*√7 => 15+3√7-5√7-7 => 8-2√7
Final answer:
8-2√7

Answer:
The solutions are 1 , -6
Step-by-step explanation:
∵ (x + 2)(x + 3) = 12
∴ x² + 3x + 2x + 6 - 12 = 0
∴ x² + 5x - 6 = 0
∴ (x - 1)(x + 6) = 0
∴ x - 1 = 0 ⇒ ∴ x = 1
∴ x + 6 = 0 ⇒ x = -6
