Answer:
B
Step-by-step explanation:
The entry A is the result of multiplying - x and 3x, that is
- x × 3x = - 3x² → B
5. c = 13
6. b=6
7. b=8
8. a=30
9. a=2√3
Step-by-step explanation:
We will use Pythagorean theorem in each to find the length of missing side.
5. a=12, b=5
Putting in formula
Taking square root on both sides
Therefore,
c = 13
6. a=8 , c=10
Putting in formula
Taking square root on both sides
b=6
7. a=15, c=17
Putting in formula
Taking square root on both sides
b=8
8. b=40, c=50
Putting in formula
Taking square root on both sides
a=30
9. b=2 , c=4
Putting in formula
Taking square root on both sides
a=2√3
