1.Proportional reasoning compares ratios to answer questions. We can use proportional reasoning to solve some questions directly, such as which size of laundry detergent is the cheapest per load, or what the dimensions of the model car should be.
3.The question is how many ways
There are as a many ways to solve a math problem as you can think of.(Some are shorter or easier than others.)
Essentially, an innfinite number.
sorry I have no idea other questions
Answer:
Step-by-step explanation:
(x - h) {}^{2} + (y - k) {}^{2} = {r}^{2}(x−h)
2
+(y−k)
2
=r
2
here
r = 7. (the circle is symmetrical with y - axis )
h = 0. and k = 1
Thus equation of circle is,
(x - 0) {}^{2} + (y - ( - 1)) {}^{2} = {7}^{2}(x−0)
2
+(y−(−1))
2
=7
2
x^2 + (y+1)^2 = 49
Answer:
8x + 8
Step-by-step explanation:
There are 8x and the numbers equal 8.
If you go from x + 6, the numbers add up to 8
