(x+6)(x+2)
Simplifying
(x + 6)(x + 2)
Reorder the terms:
(6 + x)(x + 2)
Reorder the terms:
(6 + x)(2 + x)
Multiply (6 + x) * (2 + x)
(6(2 + x) + x(2 + x))
((2 * 6 + x * 6) + x(2 + x))
((12 + 6x) + x(2 + x))
(12 + 6x + (2 * x + x * x))
(12 + 6x + (2x + x2))
Combine like terms: 6x + 2x = 8x
(12 + 8x + x2)
Answer:
Explanation:
1.
x^2 - 10x + 24
= (x - 6)(x - 4)
2.
x^2 - 12x + 27
= (x - 9)(x - 3)
3.
x^2 - 13x + 36
= (x - 9)(x - 4)
4.
x^2 - 5x - 14
= (x - 7)(x + 2)
5.
x^2 + x - 20
= (x + 5)(x - 4)
6.
x^2 - 3x - 40
= (x - 8)(x + 5)
7.
x^2 + 2x - 48
= (x - 8)(x + 6)
8.
x^2 + 10x - 24
= (x - 2)(x + 12)
9.
x^2 - 7x - 44
= (x - 11)(x + 4)
10.
x^2 + x - 2
= (x + 2)(x - 1)
11.
x^2 + 2x + 1
= (x + 1)(x + 1)
12.
x^2 - x - 6
= (x - 3)(x + 2)
Answer:
20
Step-by-step explanation:
Given data
Let the number of magic tricks be x
we are told that she knows 70% of card trick which is 14 card tricks
hence we have
70/100*x= 14
0.7x= 14
x= 14/0.7
x=20
Hence the number of magic tricks she knows is 20
