Answer:
p² -16pq + 36q²
Step-by-step explanation:
Given
(- 
p + 6q)²
= (- p + 6q)(- p + 6q)
Each term in the second factor is multiplied by each term in the first factor, that is
- p(- p + 6q) + 6q(- p + 6q)
= p² - 8pq - 8pq + 36q² ← collect like terms
= p² - 16pq + 36q²
So, there will be 40 green cars. if we want the ratio to be 1:3, we will need there to b three times as many silver cars as green cars: 40*3=120.
we already have 20 silver, so we need to add 120-20, that is 100 silver cars!
The area ratio is 1:16 meaning that the old area is 1 while the new area is 16. So this is another way of saying "the area is multiplied by 16"
Take the square root of each part of the ratio of 1:16 and we get 1:4
So this is the scale factor. It tells us how the linear components of the circles relate to one another. If the circumference of the smaller circle is 1,then the larger circle has a circumference of 4.
Therefore, the circumference has been multiplied by 4
Answer:
what function
Step-by-step explanation:
Answer: $230
