What is the coefficient of x in the division (18x^3 + 12x^2 – 3x) / 6x^2?A) 3
B) 2
C) -0.5
D) -3
Answers
(18x^3 + 12x^2 – 3x) / (6x^2) = (6x^2 + 4x - 1) / (2x) = 3x + 2 -1/(2x)
The correct result would be A) 3.

Part A: Is Malia's solution correct or incorrect? If the solution is incorrect, explain why it is incorrect and show the correct steps to solve the equation.
Part B: How many solutions will this equation have?
Answers
Answer:
Part A- wrong step number 2 by Malia
Part B - Only 1 solution
Step-by-step explanation:
Given steps are :
Step 1: 6x = 48
Step 2: x = 48 – 6
Step 3: x = 42
Part A:
The second step is wrong. Malia subtracted 6 from 48, but she should not have done it. She should have divided both sides by 6, to get the value of 'x' which is 8.
The correct step should be :
Divide both sides by 6,
Part B:
The equation has only 1 solution.
for part A
FOR PART B
there is one solution
The sum of its angle measures is 360°.
It has four congruent angles.
It has four congruent sides.

The perimeter of the triangle ΔADE will be 30 units.
What is the perimeter of a triangle?
Let the triangle be ABC.
Then the perimeter of the triangle will be
Perimeter = AB + BC + CA
AC and BD are perpendicular bisectors of each other.
The diagram is shown below.
P = AD + DE + EA
P = 13 + 12 + 5
P = 30 units
More about the perimeter of a triangle link is given below.
#SPJ2
THE CORRECT ANSWER IS 30.
AC and BD are perpendicular bisectors of each other.
=> ABCD is rhombus.
AD = 13
AE = √(13^2 - 12^2) = 5
the perimeter of triangle ADE = 13+12+5 = 30

Answer: The answer is false.
Step-by-step explanation: We are asked whether The Federal Reserve Bank is responsible for minting new coins.
The answer to this question is a clear NO. The Federal Reserve does not control the printing or minting of new coins.
In fact, The Treasury controls and operates the printing presses. The United States Mint takes the responsibility for producing coins and the Bureau of Engraving and Printing (BEP) produces currency notes. The work of Federal Reserve banks is to make the arrangement for receiving new coin shipments for the new upcoming year.
Thus, the answer here is NO.

Slope-intercept form y = mx + b
where m------> slope
b-------> y-intercept
m= (y1-y2)/(x1-x2)
P1(-3,5) (x1,y1)
P2(2,10) (x2,y2)
m= (5-10)/(-3-2)
m= (-5)/(-5)
m=1
Until now, the equation is y=mx+b
y=1.x+b
y=x+b
But, whe can plug the point P2(2,10) in y =x+b
10 =2 + b
10 - 2 = b
b= 8
Then, the equation is y=mx+b
y= x+8 <-------------------Solution
Verification P1(-3,5) y = x+8 5=-3+8 Ok
P2(2,10) y = x +8 10 = 2+8 Ok
