A dilation of 27 is the answer because 27*20=540
The elements you can see in the reaction are Calcium(Ca), Hydrogen(H), and Oxygen(O). So there are 3 elements in the chemical reaction.
The values of a and b are -3 and -1 respectively
x³ + ax ²+ bx + 6 has (x - 2) as a factor. Therefore,
(2)³ + a2²+ 2b + 6 = 0
8 + 4a + 2b + 6 = 0
4a + 2b = -14
x³ + ax ²+ bx + 6 leaves a remainder 3 when divided by (x - 3). Therefore,
(3)³ + a3²+ 3b + 6 = 3
27 + 9a + 3b + 6 = 3
9a + 3b = 3 - 33
9a + 3b = -30
<h3>Simultaneous equation:</h3>
4a + 2b = -14
9a + 3b = -30
2b = -14 -4a
b = -7 - 2a
Therefore,
9a + 3( -7 - 2a) = -30
9a - 21 - 6a = -30
3a = -30 + 21
3a = -9
a = -9 / 3
a = -3
4a + 2b = -14
4(-3) + 2b = -14
-12 + 2b = -14
2b = -14 + 12
2b = -2
b = -2 / 2
b = -1

Turn 2 3/4 to an improper fraction (2*4+3=11/4). Then turn your new improper fraction to the reciprocal (switch the two numbers (4/11). Change the division sign to multiplication (3/16*4/11). Then multiply across (12/176). Then simplify by 4 to get. 3/44.
