(2x-1)(x+4) expand and simplify
Answer:
2x²+7x-4
Step-by-step explanation:
2x²+8x-x-4
2x²+7x-4
Answer:
2x² + 7x - 4
Step-by-step explanation:
(2x + 1)(x + 4)
Each term in the second factor is multiplied by each term in the first factor, that is
2x(x + 4) - 1 (x + 4) ← distribute parenthesis
2x² + 8x - x - 4 ← collect like terms
= 2x² + 7x - 4
A survey was given to people who own a certain type of car. What percent of the people surveyed were completely satisfied with the car?
Answer:
65 percent
Step-by-step explanation:
The solution is 65 %
The percentage of people who were satisfied with the car is 65 %
What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the percentage of people who were satisfied with the car be = P
Now , the number of people who were satisfied with the car = 1625
The number of people who were somewhat satisfied with car = 665
The number of people who were not satisfied with the car = 210
The total number of people surveyed = number of people who were satisfied + number of people who were somewhat satisfied + number of people who were not satisfied
Substituting the values in the equation , we get
The total number of people surveyed = 1625 + 665 + 210
The total number of people surveyed = 2500 people
So , the percentage of people who were satisfied with car P = number of people who were satisfied with the car / total number of people surveyed
Substituting the values in the equation , we get
Percentage of people who were satisfied with car P = ( 1625 / 2500 ) x 100
Percentage of people who were satisfied with car P = 0.65 x 100
Percentage of people who were satisfied with car P = 65 %
Therefore , the value of P is 65 %
Hence , the percentage is 65 %

Answer:
each tangent is 20.785 ft long
Step-by-step explanation:
since the tangent forms a right angle with the radius, and a line from P to O bisects the 60° angle:
tan 30° = 12/x
0.5774 = 12/x
0.5774x = 12
x = 20.785 ft

Find the value of x in the triangle shown below 6 2
The value of x in the stated triangle is 6.32 based on given dimensions.
The stated triangle is right angled triangle and hence will follow Pythagoras theorem. The calculation will be done using the Pythagoras formula as stated -
Perpendicular² = Base² + Height²
Keep the values in formula to find the value of x
x² = 2² + 6²
Taking square on the Right Hand Side of the equation
x² = 4 + 36
Add the digits on Right Hand Side of the equation
x² = 40
x = ✓40
Taking square root
x = 6.32
Hence, the length of x is 6.32.

If a line goes through the point (2, 7) and has a slope of -2, what is the equation of the line?
Answer:
y = -2x + 11
Step-by-step explanation:
Slope point equation:
y - y1 = m(x -x1)
y1 = 7 ; x1 = 7 , m = -2
y - 7 = -2(x - 2)
y - 7 = -2x -2*(-2)
y -7 = -2x + 4
y = -2x + 4 + 7
y = -2x + 11
