The side labeled "a" is made the longer side. These are the two congruent sides. So a > b.
We are told that the longer side is 6.3, so a = 6.3, meaning that
2a+b = 15.7
2(6.3)+b = 15.7
12.6+b = 15.7
b = 15.7-12.6
b = 3.1
The triangle has sides of: 6.3, 6.3, 3.1
The perimeter is 6.3+6.3+3.1 = 15.7
Going back to the question "which equation can be used to find the length of the base?", it sounds like either you were given a list of multiple choice answers, or you just fill in the blank. If multiple choice, then try to see which answer matches with what I wrote above. If fill in the blank, then I would just enter either 2(6.3)+b = 15.7 or 12.6+b = 15.7
<span>This is a reduction to simplest form problem. You are given 33/36. All you
need to do is to find a divisible number that can be divided to both the numerator
and denominator, 33 and 36 respectively. It’s like finding the GCF or greatest
common factor. The greatest common factor is the factor that divides both
numbers. If you try to divide them by three, 33 divided by 3 gives 11 and 36
divided by 3 gives 12. The simplest form is 11/12. </span>
Answer:
total distance= 12000+12000=24000
total time = 5+6=11
average speed of plane= 24000/11
18.44 because Pythagorean Theorem says that 12^2 + b^2 = 22^2. Then to solve you square the numbers, 144 - b^2 = 484, then subtract 144 from 484 and get 340, and the square root of 340 is 18.44.
