Answer:
D is the answer
Step-by-step explanation:
Answer: D: 40x3 +14x2+19x+15
(5x + 3) (8x2 - 2x + 5)
5x ( 8x2 - 2x + 5) +3 ( 8x2 - 2x + 5)
expanding the bracket
(40x3 - 10x2 + 25x) + ( 24x2 - 6x +15)
removing the bracket
40x3 - 10x2 + 25x + 24x2 - 6x + 15
collecting like terms
40x3 - 10x2 + 24x2 + 25x - 6x + 15
40x3 + 14x2 +19x + 15
g/f = {(-1, 2)}
domain of g/f = {-1}
Given,
f = {(-1, 4),(1, 9),(4, 0)},
g = {(-1, -8),(2, -7),(4, 8),(5, -9)}
So, Domain of f = {-1, 1, 4},
Domain of g = {-1, 2, 4, 5}
Since,
Thus, domain of g/f = Domain of f ∩ Domain of g = {-1, 4}
If x = -1,
If x = 4,
Hence, the domain of g/f = {-1}
And, g/f = {(-1, 2)}
13/12 or 1 1/12
First you would convert the 1/6 to 2/12 then add them like normal to get 13/12.

Answer: A is your answer.
Part a) The scale of the new blueprint is
Part b) The width of the living room in the new blueprint is
we know that
The scale of the original blueprint is
and
the width of the living room on the original blueprint is 6 inches
so
Find the actual width of the living room, using proportion
Find the actual length of the living room, using proportion
Find the scale of the new blueprint, divide the length of the living room on the new blueprint by the actual length of the living room
simplify
Find the width of the living room in the new blueprint, using proportion
