Answer:
The product of y and 9 is less than 21
Step-by-step explanation:
It is not possible to have an answer that equals 21 unless it is a decimal which is unlikely to happen.

Answer:
mentally "cut" the two different figures where they connect and find the area separately and then add them together:
4*15 = 60
11*10= 110
110+60= 170 sq mm
Step-by-step explanation:
i hope this helped :)
I think the question for this problem is to formulate an equation that could describe the behavior of the trend. To do this, let's see the trend first. In the first hour, the number of transactions is 10. In the 2nd hour, the transactions is 2(10) = 20. In the third hour, the transactions is 20(2) = 40. So, we can see that the trend is 10, 20, 40, 80, ....and so on. You notice that this is a geometric progression, where r=2. Thus, the equation for this will be:
Number of transactions = 10(r)ⁿ⁻¹ = <em>10(2ⁿ⁻¹), where n is the number of hours</em>
Distance between p and a, PA is twice as distance between p and b, PB. a(â’2, 6, 3), b(5, 2, â’1), PA = 2PB
Square root of [(x + 2)^2 + (y - 6)^2 + (z - 3)^2] = 2 x Square root of [(x - 5)^2
+ (y - 2)^2 + (z + 1)^2]
Removing the square roots,
[(x + 2)^2 + (y - 6)^2 + (z - 3)^2] = 4[(x - 5)^2 + (y - 2)^2 + (z + 1)^2]
x^2 + y^2 + z^2 + 4x - 12y - 6z + 4 + 36 + 9 = 4(x^2 + y^2 + z^2 - 10x - 4y +
2z + 25 + 4 +1)
x^2 + y^2 + z^2 + 4x - 12y - 6z + 49 = 4x^2 + 4y^2 + 4z^2 - 40x -16y + 8z +
120
Hence the equation of sphere = 3x^2 + 3y^2 + 3z^2 - 44x - 4y + 14z + 71
