25z^2 − 36w^2
Answers
Answer:
(5z-6w)(5z+6w)
Step-by-step explanation:
Hi there!
We're given the expression 25z²-36w² and we want to factor it.
The expression written as a difference of squares. The difference of squares is given as a²-b²=(a-b)(a+b)
Let's label the values of what is a² and b², and then try to determine what a and b are from that information
[tex]a^{2}=25z^2\\b^2=36w^2[/tex]
Alright then! Let's square root both sides to find what a and b are
[tex]\sqrt{a^2}=\sqrt{25z^2[/tex]
Which then means:
a=5z
And then for b:
[tex]\sqrt{b^2}=\sqrt{36w^2}[/tex]
b=6w
Now substitute those values into the formula
a²-b² = (a-b)(a+b)
[tex]25z^{2}-36w^2=(5z-6w)(5z+6w)[/tex]
Hope this helps!
Three companies Benfel Ltd, Cromwell Ltd and Samtec Ltd were recently launched in the Kenyan market. The companies have operated in the Kenyan market for a few months now. At the beginning of the month of August 2019, a survey on monthly brand switching behavior was conducted on a representative sample among customers of the three companies. The survey revealed that Benfel Ltd retains 70% of its customers and loses 20% to Cromwell Ltd and 10% to Samtec Ltd. Similarly, Cromwell Ltd retains 60% of its customers and loses 30% to Benfel Ltd and 10% to Samtec Ltd. Furthermore, Samtec Ltd retains 50% while it loses 30% to Cromwell Ltd and 20% to Benfel Ltd. It has been determined that there will be 3,500, 4,300 and 2,200 customers shopping with Benfel Ltd, Cromwell Ltd and Samtec Ltd respectively at the start of the month of September 2019.
i. Evaluate the distribution of the sample surveyed as at the beginning month of August 2019. (5 marks)
ii. Compare the long run state of the market amongst the three companies. (5 marks)
Answers
Evaluating the distribution sample surveyed and comparing the long run state of the market of the three companies
i) The distribution of sample as at the beginning month of August is :
Benfel limited = 5000 customers
Cromwell Ltd = 7167 customers
Samtec Ltd = 4400 customers
ii) In the long run Benfel limited will have more customers than Cromwell and Samtec because they both lose more customers to Benfel limited than Benfel loses to them. also Benfel keeps a higher percentage of its customer
i) At the Beginning of the month of August the sample size for each company respectively will be
X * 70/100 = 3500 ∴ x ( sample size at August ) = 5000 ( Benfel )
y * 60/100 = 4300 ∴ y ( sample size at August ) = 7167 ( Cromwell )
z * 50/100 = 2200 ∴ z ( sample size at August ) = 4,400 ( Samtec )
ii) In the long run Benfel limited will have more customers than Cromwell and Samtec because they both lose more customers to Benfel limited than Benfel loses to them. also Benfel keeps a higher percentage of its customers

Find m<1 if <1 is complementary to <2, <2 is supplementary to <3, and
m<3 = 126
Answers
Answer:
∠ 1 = 36°
Step-by-step explanation:
Supplementary angles sum to 180° then
∠ 2 + ∠ 3 = 180° , that is
∠ 2 + 126° = 180° ( subtract 126° from both sides )
∠ 2 = 54°
Complementary angles sum to 90° , then
∠ 1 + ∠ 2 = 90° , that is
∠ 1 + 54° = 90° ( subtract 54° from both sides )
∠ 1 = 36°

Find the value of x, given that mangle PQS = 110°.
Round the answer to one decimal place if necessary.
72+10x
(gotta find value for X)
Answers
(value of x)
So the answer is 90.8°
The correct answer would be 88.5° because 72 + 10X = 90 + X and then you have to subtract that from 110 degrees. (110 - 90 = 20, 20 / 2 = 10, so you add 10 to both sides of the equation)
110-90=20
20/2=10
10+X=10
X=0.5°
110-90+0.5 = 20.5 and that answer is rounded up to 21°
(The reason it is not rounded down to 20° is because 10/2 is 5 but you don't add it to 10 so it would be rounded down)
So the answer is 88.5°
X=88.5 ° Note: "That" in that mangle PQS = 110 ° does not refer to the answer x and therefore should be omitted. Example: Given mangle PQS = 110 °, find the value of x.
Answer: 90.8° (rounded up to the nearest degree)
Note: In free response questions, typically one decimal place is needed in the answer even if no decimal places are given in the question. For example, 1/3 is 0.33333..., and the answer is 0.3 (not 0).
88.5° should be rounded up to 90° because you add 72 + 10x which equals 90 + x and then you subtract that from 110 degrees which gives you 20 degrees. Then 20/2 = 10 so that's when you add 10 to both sides. 110 - 90 + 0.5 equals 20.5 but since 10/2 is 5 and you add that to 10 so it's now 29.5 which means you have to subtract 15 from both sides of the equation (since you can't subtract half a degree) which leaves you with 14.5 degrees, which rounds up to 15 degrees. So the answer is 88.5°.
So the correct answer should be 90°

the measure of the angles of a triangle are shown in the figure below. solve for x.
Answers
Answer:
[tex]\boxed {\boxed {\sf x= 12}}[/tex]
Step-by-step explanation:
We are asked to solve for x. We are given a triangle and all 3 angles are labeled. We know that the sum of the angles in a triangle must be 180 degrees. Therefore, the given angles: 81, 57, and (2x+18) must add to 180. We can set up an equation.
[tex]81+57+ (2x+18)= 180[/tex]
Now we can solve for x. Begin by combing like terms on the left side of the equation. All the constants (terms without a variable) can be added.
[tex](81+57+18)+2x=180[/tex]
[tex]156+2x=180[/tex]
We will solve for x by isolating it. 156 is being added to 2x. The inverse operation of addition is subtraction. Subtract 156 from both sides of the equation.
[tex]156-156+2x=180-156 \\2x=180-156 \\2x= 24[/tex]
x is being multiplied by 2. The inverse operation of multiplication is division. Divide both sides by 2.
[tex]2x/2= 24/2 \\x= 24/2 \\x=12[/tex]
In this triangle, x is equal to 12.
Answer:
x° = 12°Step-by-step explanation:
❁ Hello! ❁
The sum of the measures of the angles of a triangle is 180°.
81° + 57° + (2x + 18)° = 180°
138° + (2x + 18)° = 180°
(2x + 18)° + 138° = 180°
2x + 18° = 180° - 138°
2x + 18° = 42°
2x = 42° - 18°
2x = 24°
x° = 24° ÷ 2
x° = 12°
