Half of the product of two consecutive numbers is 105. which equation can be used to solve for n, the smaller of the two numbers? n2 n – 210 = 0 n2 n – 105 = 0 2n2 2n 210 = 0 2n2 2n 105 = 0
The equation that can be used to solve for n, the smaller of the two numbers would be n² + n - 210 = 0.
What is a quadratic equation?A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
If we use n to be the smaller number of two integer numbers, then the next consecutive number is n + 1.
The product of those two numbers would become n × (n + 1) = n (n + 1).
Half of that product is n (n + 1) / 2.
And the question states that the equation is equal to 105, so the equation becomes,
n (n + 1) / 2 = 105
Now we have to simplify that equation until we get an expression equal to one of the choices,
Multiply both sides by 2
n (n + 1) = 210
n² + n = 210
Subtract 210 from both sides
n² + n - 210 = 0
Thus, the equation formed is the quadratic equation.

What is the vertex of g(x) = 3x2 − 12x 7? (−6, −5) (−2, −5) (2, −5) (6, −5)
The vertex of g(x) = [tex]\rm 3x^2 - 12x + 7[/tex] is (2, -5), the correct option is C.
What is the vertex of the parabola?The vertex of a parabola is the highest or lowest point, also known as the maximum or minimum of a parabola.
The standard equation of the vertex of the parabola is;
[tex]\rm a(x - h)^2 + k[/tex]
Where h and k are the coordinates of the vertex of the parabola.
The given expression is;
[tex]\rm =3x^2 - 12x + 7\\\\= 3(x^2 - 4x) + 7\\\\ = 3[ (x - 2)^2 - 4)] + 7\\\\= 3(x - 2)^2 - 12 + 7\\\\= 3(x - 2)^2 - 5[/tex]
On comparing with the standard form of vertex of the parabola
h = 2 and k = -5
Hence, the vertex of g(x) = [tex]\rm 3x^2 - 12x + 7[/tex] is (2, -5).

Step-by-step explanation:
When finding a percentage of something, heres a trick. Just take the number you taking the perccentage of, and mutiply it by the percentage. In this case, 24*12.
24*12 = 288.
Now take that new number and divide it by 100. Now you have your answer. In this case,
288/100 = 2.88.

Answer:
144
Step-by-step explanation:
do 5 into 600 and u get 12 have a good day!!!
Answer:
$144
Step-by-step explanation:
first, we need to divide 600 by 50, to get them organized for the best packages. 600/50 = 12.
then, we multiply that (the 12) by the cost ($12/ea) so 12*12 which is $144 if they use the bundling.

find the area of the composite figure
Answer:
74 in²
Step-by-step explanation:
The easiest way to find the area is to imagine the rectangle as a whole rectangle, then subtract the area of the empty space.
The area of the whole rectangle can be found with:
A = b · h
A = 9 in · 11 in
A = 99 in²
So the area of the entire rectangle (with the empty space included) is 99 in².
In order to find the area of the composite figure, you need to subtract the area of the empty space, which can be found with:
A = b · h
A = 5 in · h
In order to find the height of the empty space, we can take the whole side (11 in) and subtract the values already there (4 in and 2 in).
11 in - (4 in + 2 in) = 5 in
So the height is 5 in:
A = 5 in · 5 in
A = 25 in²
The area of the composite figure is:
A = 99 in² - 25 in²
A = 74 in²

The triangles are similar. Find the value of x.
Answer:
x = 36
Step-by-step explanation:
Remark
This can be done as a proportion. A proportion consists of 2 ratios which means it has 4 parts. If you know three of them, you can solve for the 4th.
We can use the following proportion
42/14 = x / 12 Notice that both ratios have tops and bottoms that use corresponding parts. Cross Multiply
14*x = 42 * 12 Combine the right
14x = 504 Divide by 14
x = 504/14

Perimeter of parallelogram = 70 ft
-> 2x + 2y = 70 .....(1)
x = 6y (Given) .....(2)
From equations (1) & (2)
2(6y) + 2y = 70
12y + 2y = 70
14y = 70
y = 70/14
y = 5
-> x = 6*5
-> x =30
This shape is called parallelogram.
perimeter : 2(base + height)
Identify the base and height
base : x ≈ 6(y) [ as x is 6 times as large as y ]
height : y
====================================
2(base + height) = perimeter2(6(y) + y) = 70 2(7y) = 707y = 35 [ divide both sides by 7 ]y = 5Find x:
x ≈ 6(y)x ≈ 6(5)x = 30

(triangles)
Answer:
x: 8.75
y: 8.5
Step-by-step explanation:
Since the two triangles are similar, you can find the scale of LJK relevant to TRS by dividing 7/4 = 1.75
This means each side of LJK is 1.75 times greater than the respective side of TRS
Now you can plug this in to the other two sides by doing 5*1.75=8.75 and 6*1.75=10.5
This solves x, but since side LK is y+2, y is 10.5-2=8.5
x=8.75
y=8.5
