Corresponding sides have the same ratio.
(2a -5)/25 = 18/30
2a -5 = 25*18/30 = 15
a = (15 +5)/2 = 10
(3b +1)/15 = 30/18
3b +1 = 15*30/18 = 25
b = (25 -1)/3 = 8
a = 10
b = 8
Answer:
The answer is
Step-by-step explanation:
By using Pythagoras low
Then we can find that
Answer:
24
Step-by-step explanation:
To calculate the output substitute x = - 3 into f(x), that is
f(- 3) = (- 3)² - 4(- 3) + 3 = 9 + 12 + 3 = 24 ← output
