X = -b + or - radical b^2 - 4ac all over 2a
Answer:
The length of the ladder would be 32 feet.
Step-by-step explanation:
In order to find the missing value, we create a proportion. We can do this by making two fractions -- the numerator being the depicted length and the denominator being the actual length.
(1.5/4) = (12/x)
Since we don't know the actual length of the ladder, we put it in as x. Now we can cross multiply to solve.
(1.5/4) = (12/x)
1.5*x = 4*12
1.5x = 48
x = 32
The answer is 320 to find the product you can just do 4 times 8 and then add a zero
Based upon the answer choices, the correct answer is B,
X = 9
I hope this answer assisted you.
The answer will be B.
First you need to find the probability of the red marbles which is 5/12 because there is 5 marbles and if you add they up there would be 12. Then you find the probability of the green marbles which is 2/12. After that you need to multiply them. 5/12 × 2/12. Your answer will be 10/144 but then you can simply by 2.
So your answer will be 5/72.
Hope this helped.
