Answer:

Step-by-step explanation:

Are these the only choices?

A would equal 5x^2-32xi+64

B would equal 25x^2-6561

c would equal 25x^2+1024

D would equal 64x^2+25

If there is an option for (5x+8i)(5x-8i) this would be the answer

Area of larger circle = \pi *r^2=3.14(11^2)=379.94

A scale model of a car is 10 in. long. The actual car is 15 ft long. What is the scale of the model?
nikklg [1K]
Oh this question is kinda tricky. At first glance it’s 1 : 1.5 but notice the units. The model car is 10 inches long and the actual car is 15 feet long.

I think you know where to go from there, but 15 feet * 12 inches = 180 inches.

10 : 180 simplifies to 1 : 18 inches
