Answer is choice B
The ratio of the sides (first to the second) is 11/9 since we divide 22/18 and reduce that fraction
Once we know the scale factor is 11/9, we square it to get (11/9)^2 = 121/81 which is the ratio of the first area to the second area
40+5=45 is written in extended form so your answer is 45
Answer:
x² - x - 12 = 0
Step-by-step explanation:
0 = -x² + x + 12
→ Add x² to both sides
x² = x + 12
→ Minus x from both sides
x² - x = 12
→ Minus 12 from both sides
x² - x - 12 = 0
