Answer:
The length if the model is 6.875 inches.
Step-by-step explanation:
1.5 inches - > 3 feet is the same as 1 inch - > 2 feet (Same ratios: 3/1.5 = 2/1)
So since this is a linear relation between values we can use the rule of three.
1 inch(model) - > 2 feet(actual object)
x inches (model) - > 13.75 feet (car)
We cross-multiply:
1*13.75=2*x - > x= 13.75/2=6.875 inches
X=18
Because you would add 2 to both sides so it would be x=16+2 which equals 18

Answer:
9409
Step-by-step explanation:
Let's rewrite 97 as 100 - 3.
Identity used :
<u><em>(a - b)² = a² - 2ab + b²</em></u>
Now, evaluating the expression :
⇒ (100 - 3)²
⇒ (100)² - 2(100)(3) + (3)²
⇒ 10000 - 600 + 9
⇒ 9400 + 9
⇒ 9409
