The equivalent expression of 14x2 +18x + 5 is 18x + 14x2 + 5, the correct option is D.
What is a quadratic equation?A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
We are given that;
The function 14x2 +18x + 5
Now,
18x + 14x^2 + 5
This expression is equivalent to 14x^2 + 18x + 5, because it has the same terms but in a different order. You can use the commutative property of addition to rearrange the terms in any order without changing the value of the expression. For example:
14x^2 + 18x + 5 = (14x^2 + 5) + (18x)
14x^2 + 18x + 5 = (18x) + (14x^2 + 5)
14x^2 + 18x + 5 = (18x) + (5) + (14x^2)
14x^2 + 18x + 5 = (5) + (18x) + (14x^2)
All of these expressions are equivalent to each other and to the original expression.
Therefore, the equation will be 18x + 14x^2 + 5.

The integer 5 makes which of the following equations false?
A: 3m + 4 = 6m
B: −5(t − 7) = 10
C: 17 = 4x − 3
D: t + 9 = 14
Answer:
a) 3m + 4 = 6m is false.
Step-by-step explanation:
A) 3m + 4 = 6m
→ 3(6) + 4 = 6(5)
→ 18 + 4 = 30
→ [ 22 ≠ 30 ]
So, the equation is false.
B) -5(t - 7) = 10
→ -5(5 - 7) = 10
→ -5 × -2 = 10
→ [ 10 = 10 ]
So, the equation is true.
C) 17 = 4x - 3
→ 17 = 4(5) - 3
→ 17 = 20 - 3
→ [ 17 = 17 ]
So, the equation is true.
D) t + 9 = 14
→ 5 + 9 = 14
→ [ 14 = 14 ]
So, the equation is true.

Write the coordinates of the vertices after a reflection over the line x = -1.
The coordinates of the vertices after a reflection over the line x = -1 are
A’ = (-12, 3).
B' = (-1, -7)
C' = (-12, -6)
Given that the coordinates of the vertices after a reflection over the line
x = -1.
For reflection about a vertical axis (x = -1), we need only be concerned with the x-components of the vertices.
Given any point (x, y), the new x’ value would be the distance ‘d’ from the reflection axis (x -(-1)), then inverted for reflection about the axis of reflection x = -1… x’ = -1 -d… where d = (x - (-1)) = (x + 1)
x’ = -1 -(x + 1) = -x -2
Given a point from the graph as
A = (-10, -7), A’ = (-10-2 , -7) = (-12, 3).
B = (-1, -7), B’ = (-1, -7) = (-1, -7). (since on the same line.)
C = (-10, -6), C’ = (-10-2, -6) = (-12, -6).
This reflection works for vertices on either side of the reflection axis, such as if you have a triangle with some vertices on one side, and some on the other, straddling the axis.
The coordinates of the vertices after a reflection over the line x = -1 are
A’ = (-12, 3).
B' = (-1, -7)
C' = (-12, -6)

Absolute advantage theory
Adam Smith, an economist from the 18th century, introduced the idea of absolute advantage in his book The Wealth of Nations to explain how nations might profit from trade by specializing in producing and exporting the things that they can manufacture more successfully than other nations.
On the other hand, low-cost manufactured items are produced and exported by China, Thailand, and Vietnam. These three nations enjoy a distinct advantage as a result of their significantly reduced unit labor costs.

How would you sketch a plot of the line on -3x+5y=15? I got an answer with a fraction and I'm not sure if that's right
The equation y = 3/5x + 3 can be plotted to represent the graph of -3x + 5y = 15
How would you sketch a plot of the line on - 3x + 5y = 15 ?The equation of the plot is given as
-3x + 5y = 15
Divide through the equation of the plot by 5
So, we have
-3/5x + y = 3
Add 3/5x to both sides of the equation
So, we have
y = 3/5x + 3
The above means that the equation y = 3/5x + 3 can be plotted to represent the graph of -3x + 5y = 15
Hence, the equation y = 3/5x + 3 can be plotted to represent the graph of -3x + 5y = 15

The scale of a map is 1:500 000.
The area of a lake on the map is 12cm".
Calculate the actual area of the lake in km?.
The scale of a map is 1:500 000. The actual area of the lake in km is 3x10¹² km².
What is meant by the scaling on the map?The ratio between a distance on a map and its actual distance on the ground is known as the map's scale. Since scale must vary throughout a map due to the curvature of the Earth's surface, this straightforward idea is made more difficult.
• If 1 centimeter on a map corresponds to 500 000 km on the earth, then 1 cm2 would be equivalent to 1 cm² = (500000km) 2
=25×10¹⁰ km²
• The lake's exact area may now be determined by multiplying 12 cm² by 25 × 10¹⁰ km² (3 × 10¹² km²)
As a result, the distance between the towns is 0.000344 cm on the map, while the lake's real area is 3x10¹² km².

Step-by-step explanation:
Let's solve your equation step-by-step.
(x−5)²=3
Step 1: Simplify both sides of the equation.
x²−10x+25=3
Step 2: Subtract 3 from both sides.
x²−10x+25−3=3−3
x²−10x+22=0
For this equation: a=1, b=-10, c=22
1x²+−10x+22=0
Step 3: Use quadratic formula with a=1, b=-10, c=22.
x=−b±√b²−4ac/2a

=========================================================
Explanation:
The idea is to replace x with the values mentioned (one at a time) and find the paired y value
For example, if x = -1, then...
y = x² + 1
y = (-1)² + 1
y = 1 + 1
