Answer:

Step-by-step explanation:
First, factor both the denominators completely:


Now, we can see that the factors of the first denominator are -3 and 8t-3.
The factors of the second denominator are t+1 and 8t-3.
To find the LCD, multiply all of these factors together:

Notice how we only multiply 8t-3 in the equation once. This is because it was present in both denominators, unlike the other factors.
I hope this helps!
Answer:
52.48
Step-by-step explanation:
find the cross sectional area which is the triangle
triangle = 1/2 x 8.2 x 6.4 = 26.24
then, use the area to multiply by the extended length of 2
26.24 x 2 = 52.48
This is true But it can also be written as QP if there are only 2 points.<span />
Step-by-step explanation:
r=21cm
a=135
perimeter=2r+ar
=2×21+135×21
=42+2835
=2877cm
