Answer:
The correct answer is 25
Step-by-step explanation:
It is given a quadratic equation,
x² – 8x = 9
<u>To find the number to be added</u>
The given equation be x² – 8x = 9
here we have to add (b/2)² - the square of half the coefficient of x,
Here b = -8
(b/2)² = (-8/2)² = -4² = 16
Add both side with 16
x² – 8x + 16 = 9 + 16
(x - 4)² = 25
(x - 4)² = 5²
The minimum product would be a negative number with the maximum absolute value.
To get a negative number, the numbers must be opposite in sign.
The maximum absolute value would be attained when the two numbers have the same absolute value.
From the above, the minimum product would be -30 * 30 = -900.
(note 30-(-30)=60)
Answer:
B. supplementary angles
Step-by-step explanation:
Answer: 18
Step-by-step explanation:
The probability of this event is 424=1/4. Then the probability of 5th toss is head is 1/2. Hence, in the end the answer is 14⋅12=18.
Answer: B. 23 to 14
Since it asks for the ratio of dogs to cats the 14 has to go first. The other options are all different ways to write the same ratio. Hope this helps!
