Answer:
x= -7
Step by Step Explanation:
We can write them both like functions like this
A= 5x- 4
B= 3x+ 8
The output of A will be three times the output of B
A=3b
We replace with the functions
5x-4= 3
We solve for x
5x= -4= 9x + 24
5x- 9x= 24 + 4
-4x= 28
x= 28 - 4
x= -7
The output that makes the out put of A 3 times the output of B is -7

Answer:
x = 2 is the solution of x^3 - x - 6
Step-by-step explanation:
(x^3) - x - 6 = 0
If x = 2,
--> (2^3) - 2 - 6
= 8 - 2 - 6 = 8 - 8 = 0.
Answer:
Dimensions of the tabletop is 2.8 cm × 2.8 cm.
Step-by-step explanation:
From the picture attached,
ABCD is a tabletop with leaves AEG, BEF, CFH and GDH.
Dimensions of the tabletop ABCD,
Length = AB
Width = BC
Coordinates of A → (1, 3)
Coordinates of B → (3, 5)
Coordinates of C → (5, 3)
Coordinates of D → (3, 1)
Length of segment = 
AB = 
= 
= 
≈ 2.8 units
BC = 
= 
= 
= 2.8 units
Therefore, dimensions of the tabletop is 2.8 cm × 2.8 cm.
Answer:
55.2 gallons/day
Step-by-step explanation:
There are 2.4 ten-hour periods in one day, so the total number of gallons per day is ...
(2.4 periods/day)(23 gallons/period) = 55.2 gallons/day
