Answer:
9
Step-by-step explanation:
9² = 81
10² = 100
81 ... 90 ... 100
90 - 81 = 9
100 - 90 = 10
9 is less than 10
Hence, √90 is closer to 9
3 because 3 packs of 12 is 36 and that is the same product as 4 packs of 9
Answer:
32² = 1024
35² = 1225
71² = 5041
46² = 2116
Step-by-step explanation:
Standard form is ax + by = c.
To change y+2 = 3(x-2) into that form, do:
y+2-2 = 3x -6 -2
-3x + y = -8
Which is not in the list, so none of the answers are right...
A = pi r^2
a = 3.14 * 97^2
a = 29,544.26 mm^2
