Determine if Louise’s answer is correct. Explain.
Answers
Answer:
SAMPLE RESPONSE
Step-by-step explanation:
Louise’s answer is not correct. She is missing the term 30x3. When squaring a binomial, it is best to write the product of the binomial times itself. Then you can use the distributive property to multiply each term in the first binomial by each term in the second binomial. Louise also could have used the formula for a perfect square trinomial, which is found by squaring a binomial.

Formula: a^2 + b^2 = c^2
so substitute the numbers like this:
10^2 + 6^2 = c^2
both 10^2 and 6^2 are perfect squares:
10 × 10= 100 and 6 × 6= 36
100 + 36= c^2
add:
100 + 36 =
136 = c^2
now in order to get rid of the squared, you put it into a radical:
√136 = √c^2
note: whatever you do on one side, you do to the other
it's easier to use the calculator for this so put √136 and you're gonna get 11.66
since it's asking you to round it to the nearest tenth:
11.66 = 11.7

Factor 10w10 – 19w9 +6w8 completely.
10w10 – 19w9 +6w8 =
Answers
Step-by-step explanation:
10w¹⁰ - 19w⁹ + 6w⁸
= w⁸(10w² - 19w + 6)
= w⁸(2w-3)(5w-2)
The value of the equation after factorization is A = w⁸ ( ( 5w - 2 ) ( 2w - 3 ) )
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
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 equation be represented as A
Now , the value of A is
A = 10w¹⁰ - 19w⁹ + 6w⁸ be equation (1)
Now , on factorizing the equation , we get
Taking the common factor as w⁸ , we get
A = w⁸ ( 10w² - 19w + 6 )
On further simplification , we get
A = w⁸ ( 10w² - 15w - 4w + 6 )
Now , on factorizing the equation , we get
A = w⁸ ( 5w ( 2w - 3 ) - 2 ( 2w - 3 ) )
And , the equation will be
A = w⁸ ( ( 5w - 2 ) ( 2w - 3 ) )
Therefore , the value of A is w⁸ ( ( 5w - 2 ) ( 2w - 3 ) )
Hence , the equation is A = w⁸ ( ( 5w - 2 ) ( 2w - 3 ) )

Answer:
a) (0,0), (-4, 1), (-1,2)b) NoneStep-by-step explanation:
There are two ways of solving similar problems. One- substitute x and y with respective coordinates and verify if the inequalities are correct. Two- graph the lines and see if the points are in the intersection zones.We'll go with the first method. Remember both inequalities should be correct for the same point to accept it as a solution.Given points

Answer:
a. all points are part of the solution set
b. no points are in the solution set
Step-by-step explanation:
Graphs of the two systems of inequalities are attached.
a) The red area on the graph is the solution. The two inequalities can be combined to one compound inequality:
x -1 < y < -1/2x +2
The two boundary lines intersect at x-1 = -1/2x +2 ⇒ x = 2, so there are no points in the solution set with x-values of 2 or greater.
All of the given points are in the solution set.
__
b) The green area of the graph is the solution. Solving each inequality for y gives ...
x -2y ≥ 4 ⇒ 1/2x -2 ≥ y
2x -y ≥ -1 ⇒ 2x +1 ≥ y
The allowed values of y must be less than or equal to the minimum of these limits. The limits have the same value at 1/2x -2 = 2x +1 ⇒ x = -2, so the solution set is the area below and right of that intersection point of the two boundary lines.
None of the given points are in the solution set.
