Answer:
x=5/-3
Step-by-step explanation:
(x+2)(x-4) = 7
FOIL
- 2x - 8= 7
Subtract 7 from both sides
- 2x - 15 = 0
Factor
(x-5)(x+3)
x=5
-3 is extraneous side lengths cannot be negative

Step-by-step explanation:
Remark
f(x) = 9x^2 - 5x + 3 is given. The notation means that wherever you see and x on the right, you replace it with the x in the brackes on the left. f(3) is a direction, not anything you have to adjust or manipulate.
Solution
f(-3) = 9*(-3^2) - 5*(-3) + 3 (-(3))^2 = -3 * -3 = 9 two minuses make a +
f(-3) = 9*(-3)(-3) + 15 + 3 -3 times an operation of minus equals a +
f(-3) = 9 * 9 + 15 + 3
f(-3) = 81 + 15 + 3
Answer: f(-3) = 99
The probability that a point is chosen at random in the shaded region will be 0.25.
<h3>What is probability?</h3>
Its simple notion is that something will most likely occur. The favorable event's proportion to the overall number of occurrences.
Probability = (Favorable event) / (Total event)
The area of the shaded circle below is 78.5 square inches.
The area of the large circle is 314 square inches.
A shaded circle is inside of a larger unshaded circle.
Then the probability that a point is chosen at random in the shaded region will be
P = 78.5 / 314
P = 1 / 4
P = 0.25
Then the correct option is A.
