Answer: 27g+12q-8qr+42d-90
Step-by-step explanation:
3(9g+8),-6(9-2q) -8(9r+6) and 6(-2+7d)
=27g+24-54+12q-8qr-48-12+42d
=27g+12q-8qr+42d-90
Answer:
m= -20
Step-by-step explanation:
<span>The distributive property is: a(b + c) = ab + ac. In this expression, the example would be 8(54 + 0) = (8 x 54) + (8 x 0). The cost of eight family passes is therefore equal to 8 x 54. $432 is the answer.</span>
Answer:
(x - 1)( x - 2) (x + 2) = x³ -x² -4x + 4.
Explanation:
1) Given equation:
3 5x x + 2
- ------- + -------- = ---------------
x + 2 x - 1 x² - 3x + 2
2) So, the denominators are x + 2, x - 1, and x² - 3x + 2
3) The LCD is the product of the common and non common factors raised to the greatest power.
4) x + 2, and x - 1 are already prime factors
5) Factor x² - 3x + 2
x² - 3x + 2 = (x - 2)(x - 1)
6) Then, the factors are x + 2, x - 1, and x - 2, and the LCD is the product of them:
(x - 1)( x - 2) (x + 2)
7) If you expand the products (distributive property) you get:
x³ -x² -4x + 4.
Answer:
C. -186,205
Step-by-step explanation:
636,854 - 827,155 + 684,862 - 680,766
=> 1,321,716 - 1,507,921
=> -186,205
