My calculator shows that
(2.1)/(1.488) = 1.41129
which is approximate. If you want the result to two decimal places, then it would be 1.41 and not 1.40
Try 1.41 and it should work out, assuming your teacher wants two decimal places.

3x^2-11x-20
Answer:
(3x-4)(x+5)
Step-by-step explanation: First set up a diamond problem. Find what two numbers add to 60 since 3*20 and add to -11. That would be 15 and -4. Then draw a 2x2 box, and put in 3x^2 the -20, 15x and -4x. Then find the factors. Hope that helped! :)

Answer:
The numbers are 12 and 8
Step-by-step explanation:
let the numbers be x and y :
[tex]x + y = 20 - - - (a) \\ x - y = 4 - - - (b)[/tex]
add (a) and (b):
[tex]2x + 0y = 24 \\ 2x = 24 \\ x = 12[/tex]
find y:
[tex]x + y = 20 \\ 12 + y = 20 \\ y = 20 - 12 \\ y = 8[/tex]

Solution:-Given,
Population of Canada = 32 million (1/10 of that of the USA)
=> Let the population of the USA be 'x'.
Now,
→ x/10 + 32 (million)
→ x = 32 × 10
→ x = 320 million.
(The number of zeros in 1 million is 6, so the number of zeros in 320 million will be 7)
Answer:-320000000 or 320 million.

(9 + 2i)(9 - 2i)
Answer:
It can't be expressed in that form
Step-by-step explanation:
From difference of two squares:
[tex]{ \boxed{(a + b)(a - b) = ( {a}^{2} - {b}^{2} )}}[/tex]
a » 9
b » 2i
[tex](9 + 2i)(9 - 2i) = \{ {(9)}^{2} - {(2i)}^{2} \} \\ \\ = (81 - 4 {i}^{2} )[/tex]
but i² is -1 [ complex numbers ]
[tex] = \{81 - 4( - 1) \} \\ = 81 + 4 \\ = 85[/tex]
Answer:
[tex](9 + 2i)(9 - 2i) \: \\ this \: can \: be \: wrtten \: as \: \\ {9}^{2} - {2i}^{2} = 81 - 4 \times - 1 \\ = 81 + 4 = 85 \\ then \: 85 + 0i \\ thank \: you[/tex]

Answer:
The GCF is going to be 9
Step-by-step explanation:
When finding the GCF, you want to do prime factorization of each number.
18's prime factorization is, 2 × 3 × 3, which equals 18
36's prime factorization is 2 × 2 × 3 × 3, which equals 36
45's prime factorization is 5 × 3 × 3, which equals 45
Now all you have to do is find the factors common in each one, which is 2 three's. You then multiply 3 × 3 = 9. That is your answer

Answer:
[tex]x=-\frac{5}{3}\quad \mathrm{or}\quad \:x=3[/tex]
Step-by-step explanation:
[tex]2\left|3x-2\right|=14[/tex]
⇒ Divide both sides by 2
[tex]\frac{2\left|3x-2\right|}{2}=\frac{14}{2}[/tex]
[tex]\left|3x-2\right|=7[/tex]
⇒ Now, apply absolute rule:- if |x|=a,a > a than x=a or x=-a
[tex]3x-2=-7\quad[/tex]
or...
[tex]3x-2=7[/tex]
Now,
[tex]3x-2=-7[/tex]
⇒ Add 2 to both sides:-
[tex]3x-2+2=-7+2[/tex]
[tex]3x=-5[/tex]
⇒ Divide both sides by 3:-
[tex]\frac{3x}{3}=\frac{-5}{3}[/tex]
[tex]x=-\frac{5}{3}[/tex]
[tex]3x-2=7[/tex]
⇒ Add 2 to both sides:-
[tex]3x-2+2=7+2[/tex]
[tex]3x=9[/tex]
⇒ Divide both sides by 3:-
[tex]\frac{3x}{3}=\frac{9}{3}[/tex]
[tex]x=3[/tex]

Consider the given line segment. If AC is 39cm long, answer the following questions:
A
B
9x+7
-3x+20
AB -
BC =
Is point B the midpoint? (yes or no)
The point which is equidistant from the endpoints of a line segment, hence, marking the middle point of the line is called the midpoint. Therefore, Point B is not the midpoint
AB + BC = AC
9x + 7 + (-3x + 20) = 39
9x + 7 - 3x + 20 = 39
6x + 27 = 39
6x = 39 - 27
6x = 12
x = 12 / 6
x = 2
9x + 7 = - 3x + 20
9(2) + 7 = - 3(2) + 20
25 = 15
Hence,
Since, AB ≠ BC, then B is not the midpoint
