Answer:
f(10) = 342
Step-by-step explanation:
f(x) = 3x² + 6x - 18
f(10 = 3(10)² + 6(10) - 18
f(10) = 3(100) + 60 - 18
f(10) = 300 + 60 - 18
f(10) = 360 - 18
f(10) = 342
Since the scale factor is 3:1 you can multiply the length of the side of the triangle to the right by 3 to make the ratio 3:3
the equation would be:
2x+5 = 45
subtract 5 from both sides
2x = 40
divide both sides by 2
x = 20
hope this helps
I think it is 15 because 3*5=15
Step-by-step explanation:
Add 1 to both sides of the equation:
Note that
Likewise,
Therefore,
It would be 6:4:3 because you divide each number by a factor they all have in common, which would be 7.
