C is the answer you're looking for
Answer:
X<12
Step-by-step explanation:
x² - x - 12 <0 any number without a power is to power 1.
x² - x^1 - 12<0
x^1 - 12 <0
x - 12 <0 any to the power 1 is that same number example p^1=p
x - 12 + 12<0 + 12
x<12
To start off this is multiplication and not addition nor subtraction where you have to line up your numbers like 46.93
+ 1.98
No, instead you put them in any order such as
46.93
x. 1.98
---------------
37544
421370
+ 469300
------------------
92.9214 ------> This is your answer!
1)Multiply the 3 in 46.93 to the 8 in 1.98 which is 24. 2) Then you multiply the 9 in 46.93 to the 8 in 1.98 which gives you 72 and don't forget to add the 2 from 24. You get 74. 4)You then multiply the 6 in 46.93 to the 8 in 1.98 and you get 48, add the 7 from 74, and you get 55. 5) You multiply the 4 in 46.93 to the 8 in 1.98 and you get 32, plus the 5 from 55 and you get 37. Your first answer should be 37544.
6) After you get this answer, you add a zero underneath the 4 in the one's place from your previous answer. 7) This step might be a little hard to remember, but you do the same procedure as you were doing in steps 1-6. This time on the other hand, you multiply each value in 46.93 to the 9 in1.98. 8)After completing those exact steps, your secondary answer should be 421370. 9) Once having this answer, you multiply 46.93 to the 1 in 1.98 and your third answer should be 469300. 10) The next step is to add up all three of your answers together and you get the final answer. You should be getting 929214. 11) The last and final step is to count the spaces of decimals your multiples' have which are 4, and you move 4 spaces to the left and you get 92.9214.
a right triangle has one angle that measures 90 degrees. that leaves 90 degrees for the other 2 angles
90 = 40 + other angle
subtract 40 from each side
50 = other angle
Answer = 50 degrees
