factor the trinomial x^2-2x-35
Answer:
(x + 5)(x - 7)
Step-by-step explanation:
x² - 2x - 35
Now we need to find two numbers whose product will be 35 and sum or difference will be 2. They are 7 and 5.
7 x 5 =35
7 - 5 = 2
So
= x² + 5x - 7x - 35
Taking x common from 1st two terms and -7 from last two.
= x(x + 5) - 7(x + 5)
Taking (x + 5) common
= ( x + 5)(x - 7)
The trinomial x² - 2x - 35 can be factored into the product of two binomials, (x - 7) and (x + 5).
What is the Factorization?Factorization, also known as factoring, is the breakdown of one element into a product of other objects, or factors, which when multiplied together generate the original. For example, the number 21 factors into primes as 3 × 7, and the polynomial x² − 9 factors as (x+3)(x-3).
The trinomial is given in the question, as follows:
x²- 2x - 35
The trinomial x² - 2x - 35 can be factored as (x - 7)(x + 5). To see this, we can find two numbers that multiply to -35 and add up to -2. These numbers are -7 and 5.
To factor the trinomial, we write:
x² - 2x - 35 = (x - 7)(x + 5)
So, the trinomial x² - 2x - 35 can be factored into the product of two binomials, (x - 7) and (x + 5).

Kiara said the line with equation 28x - y = -20 has a slope of 28. . What mistake did Kiara make?
Therefore, the mistake Kiara made was to take the absolute value of the slope instead of correctly identifying the slope as a negative value.
What is equation?An equation is a mathematical statement that shows that two expressions are equal. It consists of two sides separated by an equal sign (=). The expressions on both sides of the equal sign can contain variables, constants, coefficients, and mathematical operations such as addition, subtraction, multiplication, division, exponentiation, logarithms, etc. Equations can have different types of solutions, including real solutions, complex solutions, and no solutions. Equations can be used to model a wide range of mathematical and scientific problems, and they are an essential tool for problem-solving in many fields.
Here,
The equation 28x - y = -20 is in the form of the standard linear equation Ax + By = C, where A, B, and C are constants, and x and y are variables.
To find the slope of a line from an equation in this form, we need to rearrange the equation into slope-intercept form, which has the form y =mx + b, where m is the slope of the line, and b is the y-intercept.
To do this, we need to isolate y on one side of the equation:
28x - y = -20
-y = -28x - 20
y = 28x + 20
Now we can see that the equation is in slope-intercept form, with a slope of 28, not -28 as Kiara thought.
Kiara made a mistake in identifying the slope of the line.

Answer: curve 60 angle 90
Step-by-step explanation:
I BET NO ONE KNOWS THIS y varies jointly as x and z. y=20 when x=2 and z=5 . Find y when x=3 and z=6
Hello!
If y varies jointly with x and z, it'll mean that x and z are being multiplied by a factor "k", to equal y.
To give you a visual, this is what I mean.

A rectangular dance floor has an area of 96 square feet and a length of 8 feet.
What is the width of the dance floor?
Enter your answer in the box
Answer:
12 is the width
Step-by-step explanation:
1. To solve this problem we must first set up an equation:
96a=8l ×?w
2. this is what this equation means 96(area) equals 8(length) times what(width)
3. so we must find out what we must multiply by 8 to get 96
4. to do this we will divide 96 by 8

To solve (a) to (d), we simply apply the following binomial probability formula
[tex]P(x) = ^nC_xp^x(1-p)^{n-x}[/tex]
Solving (a):
[tex]x = 1[/tex]
So, we have:
[tex]P(x = 1) = ^4C_1 * (0.18)^1 * (1-0.18)^{4-1}[/tex]
[tex]P(x = 1) = ^4C_1 * (0.18)^1 * (1-0.18)^{4-1}[/tex]
[tex]P(x = 1) = 4 * (0.18)^1 * (1-0.18)^3[/tex]
[tex]P(x = 1) = 0.3970[/tex]
Solving (b):
[tex]x = 2[/tex]
So, we have:
[tex]P(x = 2) = ^4C_2 * (0.18)^2 * (1-0.18)^{4-2}[/tex]
[tex]P(x = 2) = 6 * (0.18)^2 * (1-0.18)^2[/tex]
[tex]P(x = 2) = 0.1307[/tex]
Solving (c):
[tex]x = 3[/tex]
So, we have:
[tex]P(x = 3) = ^4C_3 * (0.18)^3 * (1-0.18)^{4-3}[/tex]
[tex]P(x = 3) = 4 * (0.18)^3 * (1-0.18)^1[/tex]
[tex]P(x = 3) = 0.0191[/tex]
Solving (d)
[tex]x = 4[/tex]
So, we have:
[tex]P(x = 4) = ^4C_4 * (0.18)^4 * (1 - 0.18)^{4-4}[/tex]
[tex]P(x = 4) = 1 * (0.18)^4 * (1 - 0.18)^0[/tex]

i need to find x, they're vertical angles
Answer:
x = 16
Step-by-step explanation:
vertical angles are equal
3x = 2x+16
x = 16
Answer: x = 16
Step-by-step explanation:
Since they are vertical angles, we can set them up equal to each other:
3x = 2x + 16
Now, we simply solve for x by subtracting 2x on both sides of the equation.
3x = 2x + 16
x = 16
forty-eight female students participated in a math fair. this represents 60% of the total students that participated. how many students participated in the math fair?
If 60 percent represents the 48 students , then the total number of student is 80
What is percentage?Percentages are essentially fractions where the denominator is 100. To show that a number is a percent, we use the percent symbol (%) beside the number. For example, if you got 75 questions right out of 100 on a test (75/100), you would have scored 75%.
Represent the total number of students by x;
therefore, 60/100 × x = 48
= 60x/100 = 48
60x = 4800
divide both sides by 60
x = 4800/60
x= 80
therefore the total number of students in the math fair is 80

Actually Welcome to the Concept of the Surface Areas and Volumes.
We know that , Volume of the cylinder = πr^2h
here, r = 5 units and h = 6 units,
hence we substitute it,
==> Volume = 3.14*(5)^2*(6)
==> Volume = 3.14*25*6
==> Volume = 471 units^3
Hence the volume of cylinder is 471 cubic units.
