28x^2-7x+8x-2
Factorization: 7x(4x-1)+2(4x-1)
(7x+2)(4x-1)
Answer:
1.000
Step-by-step explanation:
Given that,
Total output from a production system in one day = 900 units
Total labor necessary to produce the 900 units = 900 hours
Productivity refers to the measure of efficiency of the inputs or labors for accomplishing a particular task. Productivity ratio is calculated by dividing the total output of a particular product to the total inputs employed in the production of that product.
Productivity ratio:
= Total output ÷ Total input
= 900 units ÷ 900 hours
= 1.000
Answer:
18
Step-by-step explanation:
|-8| + 10 = 18
Answer:
C x=6
Step-by-step explanation:
sqrt(x+3) = x-3
Square each side
(sqrt(x+3))^2 = (x-3)^2
x+3 = (x-3)^2
x+3 = (x-3)(x-3)
FOIL
x+3 = x^2 -3x-3x+9
Combine like terms
x+3 = x^2 -6x+9
Subtract x from each side
x-x+3 = x^2 -6x-x +9
3 = x^2 -7x +9
Subtract 3 from each side
3-3 = x^2 -7x +9-3
0 = x^2 -7x+6
Factor
0 = (x-6)(x-1)
Using the zero product property
x-6=0 x-1 =0
x=6 x=1
Since we squared we need to check for extraneous solutions
x=1
sqrt(1+3) = 1-3
sqrt(4) = -2
2=-2
False
Extraneous
x=6
sqrt(6+3) = 6-3
sqrt(9) = 3
3=3
True solutions
