Answer with step-by-step explanation:
Let's start by listing out the equation; w × l × 2l = v. If we simplify this equation, we would get w × [tex]2l^2[/tex] = v. This would mean the correct choice is B, because it shows the key equation, just written differently.

Step-by-step explanation:
I forgot what it's called but basically 101+x+29= 180 because it's straight line. So you can just go ahead and add 29 and 101 to get 130 and subtract that from 180 to get 50.

what is the factor of these general trinomial 2x2 - 5x - 12??
Answer:
(x - 4)(2x + 3)
Step-by-step explanation:
Given
2x² - 5x - 12
Consider the factors of the product of the coefficient of the x² term and the constant which sum to give the coefficient of the x- term.
product = 2 × - 12 = - 24 and sum = - 5
The factors are - 8 and + 3
Use these factors to split the x- term
2x² - 8x + 3x - 12 ( factor the first/second and third/fourth terms )
= 2x(x - 4) + 3(x - 4) ← factor out (x - 4) from each term
= (x - 4)(2x + 3) ← in factored form
The factors are (x - 4) and (2x + 3)
Please help me? I really need the answer.
Answer:
20
Step-by-step explanation:
Let the number of people be x.
Rs. 1000 is distributed equally among x people, so each person gets 1000/x.
If there were 5 people more, there would be x + 5 people.
Then, each person would get 1000/(x + 5). Each of the x + 5 people would get Rs. 10 less than before.
1000/x - 10 = 1000/(x + 5)
Multiply both sides by the LCD, x(x + 5).
x(x + 5) × 1000/x - x(x + 5) × 10 = x(x + 5) × 1000/(x + 5)
(x + 5) × 1000 - (x² + 5x) × 10 = x × 1000
1000x + 5000 - 10x² - 50x = 1000x
5000 - 10x² - 50x = 0
10x² + 50x - 5000 = 0
x² + 5x - 500 = 0
(x + 25)(x - 20) = 0
x + 25 = 0 or x - 20 = 0
x = -25 or x = 20
The actual number of people is 20.
Check:
Rs. 1000/20 = Rs. 50
Rs. 1000 divided equally among 20 people gives Rs. 50 per person.
If there are 5 people more, then there are 25 people.
Rs. 1000/25 = Rs. 40
Rs. 1000 divided by 25 people gives Rs. 40 per person which is Rs. 10 less per person.
Our solution is correct.
What does (7x - 10) - (-6x - 8)
Answer:
13x - 2
Step-by-step explanation:
Use the distributive property to eliminate the parentheses. 1(7x - 10) -1(-6x - 8) so using the distributive property 7x - 10 + 6x + 8. Next, combine the like terms. 13x - 2

Answer:
There is a 1/10 chance you draw an A and then D 10% chance
Step-by-step explanation:
Probablitiy of drawing a D is 1/5, If the card is not replaced, then there are only 4 cards left. Probability of drawing an A is 2/4 (1/2)

If f(-7)=14, what order pair does this represent?
Answer:
(-7, 14)
Step-by-step explanation:
The function f(x) is equal to the y-coordinate. The value inside of the parenthesis is the x-coordinate, so it would be -7 in this problem.

The sum of 5 consecutive even numbers is 200
Answer:
36, 38, 40, 42, 44
Step-by-step explanation:
We can denote an even number as 2n (where n is a natural number).
Each consecutive even number will be 2 more than the previous number.
Let 1st number = 2n
⇒ 2nd number = 2n + 2
⇒ 3rd number = 2n + 4
⇒ 4th number = 2n + 6
⇒ 5th number = 2n + 8
Sum of all 5 numbers is 200.
⇒ 2n + 2n + 2 + 2n + 4 + 2n + 6 + 2n + 8 = 200
⇒ 10n + 20 = 200
⇒ 10n = 180
⇒ n = 18
If n = 18, then 2n = 36
Therefore, the numbers are 36, 38, 40, 42, 44
A window seat is in the shape of a trapezoid. Write the polynomial that represents the area of the window seat.
The polynomial that represents the area of the trapezoid shaped window is: 1/2(8x² - 14x - 15).
What is the Area of a Trapezoid?Area of trapezoid = 1/2(a + b)h, where a and b are length of the parallel sides, and h is the height.
Given:
a = 3x + 5
b = x - 2
h = 2x - 5
Thus:
Area of trapezoid = 1/2(3x + 5 + x - 2)(2x - 5)
Area of trapezoid = 1/2(4x + 3)(2x - 5)
Area of trapezoid = 1/2(8x² - 14x - 15)
Therefore, the polynomial that represents the area of the trapezoid shaped window is: 1/2(8x² - 14x - 15).

Which of the following is an equation of line l in the xy plane above
A) 1 = 1
B) y = 1
C) y = x
D) v = x + 1
Answer:
Option (D)
Step-by-step explanation:
Let the equation of the line be,
y = mx + b
where m = slope of the line
b = y-intercept
Slope of the line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Since, line 'l' is passing through two points (0, 1) and (-1, 0),
Therefore, slope 'm' = [tex]\frac{1-0}{0+1}[/tex] = 1
y-intercept 'b' = 1
Therefore, equation of the line will be,
y = 1(x) + 1
y = x + 1
Option (D). will be the answer.

Formula)
1. The sides of a triangle are 8cm, 15cm and 17cm, find its perimeter and its area. Also find the lengt
altitude drawn on the side with length 17cm.
Step-by-step explanation:
a=8cm
b=15cm
c=17cm
s=a+b+c/2
=8+15+17/2
=40/2
=20
Using heron's formula,
ar. of triangle= √s(s-a)(s-b)(s-c)
=√20(20-8)(20-15)(20-17)
=√20×12×5×3
=√2×2×5×2×2×3×5×3
=2×2×3×5
=60cm²
On side 17cm,
Ar. of triangle=1/2×b×h
