Answer:
x = StartFraction negative 8 Over 3 EndFraction, –2
Step-by-step explanation:
3x² + 14x + 16 = 0
3x² + 6x + 8x + 16 = 0
(3x² + 6x) + (8x + 16) = 0
3x(x+2) + 8(x+2) = 0
(x+2)(3x+8) = 0
x = -2 , x = -8/3.

In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis)
Answer:
the roots are {-4/3, 4/3}
Step-by-step explanation:
Begin the solution of 11=6|-2z| -5 by adding 5 to both sides:
11=6|-2z| -5 becomes 16 = 6|-2z|.
Dividing both sides by 12 yields
16/12 = |-z|
There are two cases here: first, that one in which z is positive and second the one in which z is negative.
If z is positive, 4/3 = -z, and so z = -4/3, and:
If z is negative, 4/3 = z
Thus the roots are {-4/3, 4/3}
The gravity is 1.5m\s^2
Further explanation:
The weight of any object is given by the product of mass and gravity of the object
Let
m denote the mass of object
g be the gravity
and
w be the weight
Then the statement can be mathematically written as:
Given
m=300kg
w=450N
Putting the values of m and w into the formula
The gravity is 1.5m\s^2

Answer:
60 hours
Step-by-step explanation:
300 + 5x = 10x
subtract 5x from both sides to cancel 5x on the left
300 = 5x
divide both by 5
60 = x
