Step-by-step explanation:
(2x^2 + 10x + 7x + 35) - (x^2 - 3x + 5x - 15)
x^2 + 15x + 50
(x + 5)(x + 10)
x = -10
Step-by-step explanation:
a
(x+5)(2x+7)-(x+5)(x-3)
factorize (x+5) out
(x+5)[(2x+7)-(x-3)]
(x+5)(2x+7-x+3)
(x+5)(2x-x+7+3)
(x+5)(x+10)
b. to get the zeros of the equation,
(x+5)(x+10)=0
x+10=0
x=-10

Find the 13th term of the arithmetic sequence -3x+7, -5x+3, -7x-1, ...
Answer:
a₁₃ = - 27x - 41
Step-by-step explanation:
The nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 3x + 7
d = a₂ - a₁ = - 5x + 3 - (- 3x + 7)
= - 5x + 3 + 3x - 7
= - 2x - 4
Then
a₁₃ = - 3x + 7 + 12(- 2x - 4)
= - 3x + 7 - 24x - 48
= - 27x - 41
In a right triangle, if a = 8 and c = 17, what is the correct setup to find the value of b?
Answer:
b = 15
Step-by-step explanation:
Assuming that the question is referring c as the hypothenuse, the Pythegorean theorem states: [tex]a^2+b^2=c^2[/tex].
Thus, [tex]b=\sqrt{c^2-a^2}=\sqrt{17^2-8^2}=15[/tex].
So b is 15.
Answer: b = 15
Step-by-step explanation:
Here, we need to know the formula for the relationship between the three sides of the right triangle: a² + b² = c².
a and b are legsc is hypotenuse--------------------------------------------------------------------
Given
a = 8
c = 17
Solve
a² + b² = c²
(8)² + b² = (17)²
64 + b² = 289
b² = 225
b = √225
b = 15Hope this helps!! :)

Security deposit is paid in advance to protect landlords against nonpayment.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
A security deposit is a sum of money paid by a tenant to a landlord or property manager before moving in, with the purpose of protecting the landlord in case the tenant does not fulfill their obligations under the lease agreement, such as not paying rent, damaging the property or leaving it unclean at the end of the lease.
The amount of the security deposit is usually equal to one or two months' rent, and it is refundable at the end of the lease term, provided that the tenant has complied with all the terms of the lease.
If the tenant has breached the lease agreement, the landlord may use the security deposit to cover the unpaid rent or any damages caused by the tenant.
Hence, Security deposit is paid in advance to protect landlords against nonpayment.

The list shows the value of five accessories that Mary purchased for her cell phone. 29, 15, 22, 52, 38 What is the mean absolute deviation of the numbers in the list?
Answer:
11.04
Step-by-step explanation:
Given the data:
29, 15, 22, 52, 38
The mean absolute deviation :
Mean, m = Σx / n
n = sample size = 5
29 + 15 + 22 + 52 + 38 = 156
Mean = 156 / 5 = 31.2
Mean absolute deviation (MAD):
Σ|x - m| / n
(|29 - 31.2| + |15 - 31.2| + |22 - 31.2| + |52 - 31.2| + |38 - 31.2|) / 5
(2.2 + 16.2 + 9.2 + 20.8 + 6.8) / 5

Probability mathematic
Answer:
1/9
Step-by-step explanation:
Probability = Expected outcome/Total outcome
From the given pi chart,
Total outcome = 360degrees (since the total angle in a circle is 360 degrees)
Since we to find the probability of scoring a 5, we can see that the angle when he scores a 5 is 40degrees, hence;
Expected outcome = 40degrees
Pr(scoring a 5) = 40/360
Pr(scoring a 5) = 1/9
Hence the probability of scoring a 5 is 1/9
Answer:
1/9
Step-by-step explanation:
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.
Divide the number of events by the number of possible outcomes.

Solve the following quadratic by
completing the square.
y = x2 + 2x - 6
Answer:
x = - 1 ± [tex]\sqrt{7}[/tex]
Step-by-step explanation:
To solve the equation let y = 0 , that is
x² + 2x - 6 = 0 ( add 6 to both sides )
x² + 2x = 6
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(1)x + 1 = 6 + 1
(x + 1)² = 7 ( take the square root of both sides )
x + 1 = ± [tex]\sqrt{7}[/tex] ( subtract 1 from both sides )
x = - 1 ± [tex]\sqrt{7}[/tex]

how many apples would be left?
Hello!
Lets tackle each section separately!
So Robin gives the first group [tex]\frac{1}{8}[/tex] of the apples.
To find how many apples that is in standard form, we divide 40 by 8.
40 ÷ 8 = 5.
So the first group ate 5 apples.
The second group ate 4 apples.
We do not have to calculate anything since it is already in standard form.
The third group ate 20% of the apples.
To find 20% of forty we can multiply 40 by 0.20, since 0.20 is the decimal equivalent of 20%.
40 × 0.20 = 8.
The last group of children ate 8 apples.
Now we add each groups apple intake together.
5 + 4 + 8 = 17.
Finally, we subtract 17 from 40.
40 - 17 = 23.
There were 23 apples left.

Use the inequality 12>6(12x+2). Complete parts a and b.
Answer/ Step-by-step explanation:
12>6(12x+2)
Divide both sides by 6. Since 6 is positive, the inequality direction remains the same.
12/6 >12x+2
Divide 12 by 6 to get 2.
2>12x+2
Swap sides so that all variable terms are on the left hand side. This changes the sign direction.
12x+2<2
Subtract 2 from both sides.
12x<2−2
Subtract 2 from 2 to get 0.
12x<0
Product of two numbers is <0 if one is >0 and the other is <0. Since 12>0, x must be <0.
x<0

Write the repeating decimal as a mixed number.
Answer:
1 1/30
Explanation:
we know that 0.3 (recurring) is equivalent to ⅓. thus, we can find 0.03 (recurring) by adding an extra decimal behind the denominator to get 1/30.
accounting for the 1, we can now get 1 1/30.

Which equation can best be modeled by the expression 10(-4)
Check if (1,6) is the solution to the system shown below.
Answer:
NO it is not
Step-by-step explanation:
To check that, we will need to substitute the value of each of the coordinates in each of the equations
10x-y = -6
substitute 1 for x and 6 for y
we have this as;
10(1)-6 = 4
Outrightly, we can see that the given point is not a solution to the given system of equations
however, let us confirm for the second
We have this as;
-10(1) + 5(6)
= -10 + 30 = 20
so we can confirm that it does not work for any of the two and our answer is NO

Answer:
10218.75
Step-by-step explanation:
You should divide the two shapes into a rectangle and a triangle, find the area of each, then add them together like so:
For the rectangle:
37.5*22.5 = 843.75
For the triangle:
To find the base: 75 - 37.5 = 37.5
To find the height, use pythagoream theorem.
62.5² = 37.5² + b²
3906.25 = 1406.25 + b²
3906.25 - 1406.25 = 2500
√2500 = 50.
The height is 50, so 50*37.5(1/2)
= 937.5
Now add them together
937.5 + 843.75
