Answer:
26 y + 5
Step-by-step explanation:
Simplify the following:
7 3 y + 4 3 y - 3 y - 2 2 y + 5
7×3 = 21:
21 y + 4 3 y - 3 y - 2 2 y + 5
-2×2 = -4:
21 y + 4 3 y - 3 y + -4 y + 5
4×3 = 12:
21 y + 12 y - 3 y - 4 y + 5
Grouping like terms, 21 y + 12 y - 3 y - 4 y + 5 = (21 y - 4 y + 12 y - 3 y) + 5:
(21 y - 4 y + 12 y - 3 y) + 5
21 y - 4 y + 12 y - 3 y = 26 y:
Answer: 26 y + 5
Answer:
Experiment type research method
Step-by-step explanation:
Experiment type research method - In this type of research method , researcher take one or two objective as variable and done experiment on the basis of subject taken and analyze the outcome of experiment.
in this method different parameter can applied to the selected variable , to which cause and effect can be analyze. one demerits of this method is sampling method
( x² - 1 ) / ( x² + 5 x + 4 ) < 0
x² + 5 x + 4 = x² + 4 x + x + 4 = x ( x + 4 ) + ( x + 4 ) = ( x + 4 ) ( x + 1 )
Therefore:
( x - 1 ) ( x + 1 ) / ( x + 4 ) ( x + 1 ) < 0
( x -1 ) / ( x + 4 ) < 0
1.
x - 1 > 0 and x + 4 < 0
x > 1 and x < - 4 ( not possible )
2.
x - 1 < 0 and x + 4 > 0
x < 1 and x > - 4
Answer: x ∈ ( - 4, 1 ).
Total intoxicated driver = 96 + 40 = 136
P(both intoxicated driver) = 136/179 x 135/178 = 0.5762
Answer:
I believe it is 26.75
Step-by-step explanation:
Break this shape into 4 smaller shapes, the top large triangle, two bottom smaller triangles, and small bottom square. Find the area for each and add them together. So:
A = 1/2 (2)(2) + 1/2 (2)(5) + 2(2) + 1/2 3.5 (9)
A = 2+5+4+15.75
A + 26.75
