Simple. first make sure there are common denominators. There is, thus, you can now subtract.
11/12-2/12.
11-2=9
and you don't subtract denominators.
Then, 9/12
you can simplify even more by dividing both the numerator and denominator by 3. So 9/3=3 and 12/3=4
So, in simplest form, your answer is 3/4.
I rather not..............
P=2l×2w
130=2l×2(l-9)
130=2l×2l-18
148=4l
37=l
w=l-9
w=37-9
w=28
The width is 28
Answer:
for ques 18
t and w are the legs of triangle
for 15
h^2=a^2+b^2
h^2=12^2+5^2
144+25
169
so root of 169 is 13 so X is 13
I am pretty sure your answer is going to be Electron. I hope this helps!! :)
