1) (x − 5)² = (x − 5) (x − 5) = x² − 5x − 5x + 25 = x² − 10x + 25 .
2) (x + 5)² = (x + 5) (x + 5) = x² + 5x + 5x + 25 = x² + 10x + 25 .

Which two ratios represent quantities that are proportional?
Answer:
Hi, There! FrozenVines Here!
I'm here to help you Understand Better So Let's go-
20:24 is My Answer
Step-by-step explanation:
y = kx, where k is the constant of proportionality. In other words, these quantities always maintain the same ratio
proportion is an equation with a ratio on each side. It is a statement that two ratios are equal.
For example 2/5 is Equal to 4/10 this Would be A Example Of a Proportional relationship!
10,because 20 times 10 = 200
Answer:
perfect positive association
Answer:
1.6
Step-by-step explanation
You can use the angles given to figure out the degree of the angles given and then with that you set up your equation as v divided by Sin(16) is equal to 5.8 divided by sin(87) and cross multiply.
After you cross multiply you should get approximately 1.5987 is equal to v times sin(87)
you then fin out the approximation of sin(87) which should be around 0.9986 and divide both sides by 0.9986 so v is alone and your answer comes out to be v = 1.6
