Answer:
B. 3/9 = 4/12 = 1/3
Step-by-step explanation:
I calculated it logically
(x - 4)(x - 3), First find the factors of x^2 which is x and x so write that down of the left sides of both brackets. Next, find the factors of 12 that when added gives you the middle number which is -7 and i got 3 and 4 so write that down in the right sides in the brackets. Lastly you need to know the signs so now since its + 12 you need the signs that give you a positive number which is - and - but its also + and +, so look at the middle number its -7x so +3 +4 wont give you -7x but -3 - 4 will so that your answer,
Hope this helped!
We can factorize the quadratic as
and expand the right side to get
Then we find
Answer:
0.89
Step-by-step explanation:
because he has 11 biscuits in total the method of calculating probability is 1- an integer so if the integer is 11 its 1 minus 11 is 0.89
Answer:
x = 1
Step-by-step explanation:
Since, angle TUV has been divided in two parts by a ray UW
Measure of angle TUV = measure of angle TUW + measure of angle WUV
m∠TUV = m∠TUW + m∠WUV
By substituting the values of the given angles,
(9x + 1) = (7x - 9) + (5x - 11)
9x + 1 = 12x - 20
12x - 9x = 20 + 1
21x = 21
x = 1
Therefore, x = 1 will be the answer.
