Answer:
1. False
2. True
Step-by-step explanation:
If you work out the math for both you'll see that 45/100*72=32.4 and 45/72*100=62.5. Without doing the math; 45/100 is going to give you a different value than 45/72. Multiplying 100 by 45/72 is just going to add another place at the end and not change the actual value. For the second one, you are trying to figure out what part of 250 is 16% and vise versa. This means that the chunks the include that % are going to be equal. You aren't changing values, just finding chunks.
I hope this helps! Sorry if it doesn't make sense.
1.) False
take the first equation (45/100 x 72) and reduce it using the Least Common Denominator method to 9/20 x 72 to get 32 2/5. Using the same method, reduce the second equation to 5/8 (divide both the numerator and denominator to get 9) and multiply it by the LCD, 100, which would equal 62 1/2. now you have two different fractions, 32 2/5 and 62 1/2. you can either cross multiply the bigger numbers or you can reduce the equations to 9/5 x 18 and 5/2 x 25. Either way, if you cross multiply you will get your answer, false.
2.) True
Percents need to be multiplied by 0.01 (one-one hundredth.) multiply 16 by 0.01 and you get 0.16. Then you just multiply 0.16 by 250 and get 40. Now, to get the other percentage you would also multiply 250 by 0.01 and get 2.5. like earlier, you multiply the decimal, 2.5, to the other number, 16, and you get 40.
hope this helps :]

Step-by-step explanation:
study hard
If LMNP is rotated 90° clockwise around the origin then the coordinates of L' are (0, -1)
What is Coordinate Geometry?A coordinate geometry is a branch of geometry where the position of the points on the plane is defined with the help of an ordered pair of numbers also known as coordinates.
LMNP is rotated 90° clockwise around the origin.
We have to find the coordinates of L'
To rotate a point 90° clockwise around the origin, we need to swap its coordinates and negate the new x-coordinate.
So, if the coordinates of L are (1, 0), its coordinates after a 90° clockwise rotation around the origin would be:
L' = (0, -1)
Therefore, if LMNP is rotated 90° clockwise around the origin then the coordinates of L' are (0, -1)

3x + 2 ( 2x + 9 ) = 4
Answers
Answer:
3x + 2 (2x + 9) = 4
3x + 4x + 18 = 4
7x + 18 = 4
7x = -14
x = -2
Step-by-step explanation:
i think it should be -2. if im wrong sorry
Take care of the parenthesis to get the following
3x + 4x + 18 = 4
Add the X values
7x + 18 = 4
Take 18 from both sides so it looks like this
7x = 4 - 18
From this you’ll get this
7x = -14
Divide both sides by 7
x = -14 / 7
Simplify
X = 7 * - 2 / 7
Simplify
X = -2

The original blueprint of a concrete patio has a scale of 2 inches = 3 feet.
Victoria wants to make a new blueprint of the patio with a
length of 16.8 inches.
a. What is the scale for the new blueprint?
b. What is the width of the blueprint with the new scale?
Answers
The scale factor for the new blueprint will be - {K} = 3/2 and the width of the blueprint with the new scale will be 25.2 feet.
What is ratio?Ratio is a quantitative relation between two amounts showing the number of times one value contains or is contained within the other.
Given is that the original blueprint of a concrete patio has a scale of
2 inches = 3 feet. Victoria wants to make a new blueprint of the patio
with a length of 16.8 inches.
{A} -It is given that -
2 inches = 3 feet
1 inch = (3/2) feet
The scale factor for the new blueprint will be -
{K} = 3/2
{B} -The width of the blueprint with the new scale will be -
{w} = 3/2 x 16.8
{w} = 3 x 8.4
{w} = 25.2 feet
Therefore, the scale factor for the new blueprint will be - {K} = 3/2 and the width of the blueprint with the new scale will be 25.2 feet.

Trying to factor as a Difference of Squares:
1.1 Factoring: x4-175
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 175 is not a square !!
Ruling : Binomial can not be factored as the difference of two perfect squares.

1.2 Find roots (zeroes) of : F(x) = x4-175
Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0
Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers. The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 1 and the Trailing Constant is -175.
The factor(s) are:
of the Leading Coefficient : 1
of the Trailing Constant : 1 ,5 ,7 ,25 ,35 ,175

Solving a Single Variable Equation:
2.1 Solve : x4-175 = 0
Add 175 to both sides of the equation :
