Answer:
7over9 or -7over9
Step-by-step explanation:
81x power 2 - 8 = 41
(left side) (right side)
first we let the 8 from left side go to the right side,so it will be +8:
81x power 2 = 41+ 8
=49
so now we let the 81 from left side go to right side, so it will be ÷81:
x power 2= 49 over 81
and now we let the power 2 (square) go to the other side so it will become square root:
x = + - √49 over 81
at the end, you will get 2 answers which is 7 over 9 and - 7 over 9
Answer:
12
Step-by-step explanation:
Using the 30-60-90 triangle formula side AB would be double of side CB.
The angles have to have a 90 degree angle , and they have to be equal too
5 - substitute the numbers 1-10 for n in (3n-4) and add up all your answers. So (3(1)-4) + (3(2)-4)...
