You find the scale factor which is 10/4=2.5
then times that by 6.
2.5×6=15 and take 6 from 15.
15-6=9
x=9
hope it helps :-)
Answer:
try 6 i think
Step-by-step explanation:
(x^2 +5x+2.5^2) +4+5
(x+2.5)^2+9
vertex -2.5,9
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
