Answer:
x = 14
Step-by-step explanation:
14x - 196 = 0
14x = 0 + 196
14x = 196
x = 196 ÷ 14
x = 14
[tex]14x - 196 = 0 \\ \\ \implies14x = 0 + 196 \\ \\ \implies 14x = 196 \\ \\ \implies \: x = \frac{196}{14} \\ \\ \implies \: x = 14[/tex]

What is a quadratic equaton?A quadratic equation is an algebraic expression in the form of variables and constants.
A quadratic equation has two roots as its degree is two.
Given, 2x² - 2.9x - 3.6.
Now, 0.1(20x² - 29x - 36).
= 0.1{4x(5x + 4) - 9(5x + 4)}.
= 0.1{(5x + 4)(4x - 9)}.
∴ p + q + r + s = 5 + 4 + 4 - 9.
p + q + r + s = 4.

Answer:
7a is not a factor because it doesnt divide into anything.
7a is not a term because it is not only the variable.
3 is a constant because it is a number in the expression.
7a is not a coefficient because it is not just the number.
8b and 5b are like terms because they have the same variables.
None of these are true Thats false because some of the answers are right
A bowl has 8 green grapes and 15 red grapes. Henry randomly chooses a grape, eats it, and then chooses another grape. (a) What is the probability that both grapes are green? (b) What is the probability that Henry eats a red grape then a green grape?
Answer:
A. 28/253
B. 60/253
Step-by-step explanation
A. first step is to add all the grapes up which = 23
then you would put the
green grapes/ the total which would be 8/23
since henry ate one grape you would subtract 8-1 and then 23-1 and you would get 7 and 22
then you would put 7/22 and multiply 8/23 which gets you 28/253
B. first you put red grapes over total grapes which are 15/23
then,
you would do the green grapes which are 8/22
you would multiply 15/23 and 8/22 which = 60/253

What is the area of a square?A square is a four sided quadrilateral with all of the side having equal lengths. The total internal angle of a square is 360° with each side perpendicular to each other.
A square is a 4 sided polygon where all the sides are of equal length.
The area of the square is the square of any one of its side
Let a be the side of the square
Area of the square = a²
Given data ,
Let the area of the square be represented as A
Now , the value of A is
Let the area of the semicircle be S
Let the total area of the figure be T = S + A
where A = ( 4 )² = 16 cm²
And , S = ( πr² ) / 2
S = 3.14 x ( 2 )² / 2
S = 6.28 cm²
So , the total area T =6.28 cm² + 16 cm² = 22.28 cm²
Hence , the area of the figure is T = 22.28 cm²

Find the area and circumference of each shaded sector. Use 3.14 for . Round to the
nearest tenth.
Answer:
Area = 226.1 ft^2
and circumference = 61.7 ft.
Both to the nearest tenth.
Step-by-step explanation:
The area of shaded part
= 1/2 *3.14 r^2
= 1/2 * 3.14 * 12^2 = 226.1 ft^2.
Circumferences of the shaded part = diameter + length of the semicircle
= 2 *r + 3.14 * r
= 2*12 + 3.14 * 12

g ( t ) = | t | - 3 ; find g ( 3 ) , g ( -5 ) , and g ( 0 )
Answer:
g(3) = 0. g(-5) = 2. g(0) = -3
Step-by-step explanation:
simply put whatever is inside the brackets, into where t is in the equation
e.g:
|t| - 3 for g(3) is: |3| - 3 = 0
the two lines around t just mean that whatever is inside you should always turn positive. so |-1| = 1 and |-3 + 1| = 2

Answer:
Axis of symmetry: x = 5
Vertex form: y = -4(x - 5)² + 3
Step-by-step explanation:
Given ordered pairs: (2, -33) (3, -13) (4, -1) (5, 3) (6, -1)
Axis of Symmetry
As this is a parabola, it will be symmetrical.
To determine the axis of symmetry, identify two ordered pairs that have the same y-values and find their midpoint.
Two ordered pairs with the same y-value: (-4, 1) and (6, -1)
Midpoint of x = 4 and x = 6 is: x = 5
Therefore, the axis of symmetry is x = 5
Vertex form
Vertex form of a quadratic equation: y = a(x - h)² + k
(where (h, k) is the vertex)
The axis of symmetry is the x-value of the vertex of the parabola.
As we have been given the point when x = 5, the vertex is: (5, 3)
Substituting this into the formula:
⇒ y = a(x - 5)² + 3
To find the value of a, substitute any of the other points into the formula and solve for a.
Using (4, -1)
⇒ a(4 - 5)² + 3 = -1
⇒ a(-1)² = -4
⇒ a = -4
Therefore, the vertex form of the parabola is:
y = -4(x - 5)² + 3

Please help!! Thank you!!
Answer:
-0.182
Step-by-step explanation:
Given expression:
0.46 + (-0.642)It should be noted that;
1. Positive integer + (Negative integer) = Positive integer - Positive integer
a + (-b) = a - b2. Positive integer - (Negative integer) = Positive integer + Positive integer
a - (-b) = a + bOur case is point 1. Therefore,
⇒ 0.46 + (-0.642)⇒ 0.46 - 0.642⇒ -0.182A boat travels 1/5 of a mile on 7/9 gallon of gas. How many miles can the boat travel on 1 gallon of gas
Answer:Since we know the boat uses 25 gallons of gas per 64 miles, we can divide 64 miles by 25 gallons to get the rate of gallons per hour.
64 ÷ 25 = 2.56 gallons of gas every hour.
Using this information, we can multiply the amount of gas used for one hour, 2.56 gallons, by the 125 gallons of gas that the problem suggests, 125, to find the number of miles the boat can travel on the amount of gas.
2.56 x 125 = 320 miles
Answer: The boat can travel 320 miles on 125 gallons of gas.

find the surface area of each shipping package. Which package has the greater surface area? Does the same package have a greater volume?
package A: 14 x 12 x 3
package B: 11 x 6 x 8
Answer:
greater area: Ano, B has the greater volumeStep-by-step explanation:
The relevant area and volume formulas are ...
A = 2(LW +H(L +W))
V = LWH
When there are multiple instances of the calculations to be done, it is convenient to let a spreadsheet do them. The results are attached.
Figure A has the larger area.
Figure B has the larger volume.

Additional comment
The more "cube-like" the prism is, the less area it will have for the same volume. Here, package B is more "cube-like" than package A. (The ratio of largest-to-smallest dimensions is smaller for package B.)
