the first equation you would do is 3*4 as it is in the most inner parenthesis and is a multiplication equation
3*4 = 12
then add 12 to 5
12 * 5 = 17
(4^2 + 17) * 3 is what you have left
the next thing you do is the exponent
4^2 is 4*4 or 16
then add 16 to 17
16 + 17 = 33
then at the end
you multiply it by 3
33 * 3 = 99
your answer is 99

please help !!! its math problem i give brainlist What type of function is represented in the table below?
Answer:
linear is correct
Step-by-step explanation:
I have absolutely no idea what to do here. Can someone break this down for me please?
Answer:
Step-by-step explanation:
The task is to draw the parabola of the equation [tex]x^{2} -4x+4[/tex] on the given graph.
The first step we can take to doing this is to use the table on the left hand side to work out our x and corresponding y-values to use as plotting coordinates. To do this you want to substitute the given value for x which will give you a corresponding y-value.
E.g:
x | [tex]x^{2} -4x+4[/tex] | y
0 | [tex](0)^{2} -4(0)-4[/tex] | -4
Here we have gotten the coordinates (0, -4) so this will be a point on the graph.
Repeat with all other values on the table and you should get a bunch of dots which lead upwards in a curved line from a point. Extend the lines to form a parabola shape (A u-shape).
Once you have drawn the graph, label the parts.
Roots: The places where the line crosses the x-axis
Vertex: The lowest point of the parabola
Line of symmetry: The vertical line in which the parabola reflects/ is the same either side (Has equation x=_).
y-intercept: The point where the line crosses the y-axis.

Answer:
1/2
Step-by-step explanation:
3/8 + 2/8 is 5/8, 1/2 is equal to 4/8, so 5/8 is only 1/8 away from 1/2 while 5/8 is also 3/8 away from 1 or 8/8 therefore, it is closer to 1/2

pls answer the question i am mark in brainlist
Answer:
x = -2
Step-by-step explanation:
Given: [tex]\textsf{$\dfrac{x+3}{x+4}=\dfrac{x+5}{x+8}$}[/tex]
1. Cross-multiply
(x + 3)(x + 8) = (x + 5)(x + 4)
2. Distribute
⟹ (x + 3)(x + 8) = (x + 5)(x + 4)
⟹ x(x) + x(8) + 3(x) + 3(8) = x(x) + x(4) + 5(x) + 5(4)
⟹ x² + 8x + 3x + 24 = x² + 4x + 5x + 20
3. Combine like terms
⟹ x² + 8x + 3x + 24 = x² + 4x + 5x + 20
⟹ x² + 11x + 24 = x² + 9x + 20
4. Subtract x² from both sides
⟹ x² - x² + 11x + 24 = x² - x² + 9x + 20
⟹ 11x + 24 = 9x + 20
5. Subtract 24 from both sides
⟹ 11x + 24 - 24 = 9x + 20 - 24
⟹ 11x = 9x - 4
6. Subtract 9x from both sides
⟹ 11x = 9x - 4
⟹ 11x - 9x = 9x - 9x - 4
⟹ 2x = -4
7. Divide both sides by 2 to isolate the variable
⟹ 2x ÷ 2 = -4 ÷ 2
⟹ x = -2

The surface area of a cone is square units. the height of the cone is times greater than the radius. what is the length of the radius of the cone to the nearest foot? the radius is about feet.
The radius of the cone is 7 feet
How to determine the radius?The given parameters are:
Surface Area, A = 216π
h = 8/3r
The surface area of a cone is:
[tex]A = \pi r(r + \sqrt{h^2 + r^2})[/tex]
So, we have:
[tex]216\pi = \pi r(r + \sqrt{(8/3r)^2 + r^2})[/tex]
Factor out r
[tex]216\pi = \pi r(r + r\sqrt{(8/3)^2 + 1})[/tex]
Evaluate the exponent
[tex]216\pi = \pi r(r + r * 2.85)[/tex]
Evaluate the sum
[tex]216\pi = \pi r(3.85r)[/tex]
Divide both sides by pi
[tex]216 = 3.85r^2[/tex]
Divide both sides by 3.85
[tex]56.10 = r^2[/tex]
Take the square roots of both sides
r = 7 (approximately)
Hence, the radius of the cone is 7 feet

( i will give brainlist ) What is the equation of the following graph?
Answer:
y= ⅓x +2
Step-by-step explanation:
Since the graph is a linear graph, let's use the slope-intercept form to find its equation.
Slope-intercept form
y= mx +c, where m is the slope and c is the y-intercept.
The y-intercept is the point at which the graph cuts through the y-axis. In this case, the y-intercept is 2.
Thus, y= mx +2.
Let's find the slope of the graph.
First, identify 2 pairs of coordinates from the graph:
(0, 2) and (3, 3)
Next, substitute these coordinates into the slope formula below:
[tex]\boxed{ \text{slope} = \frac{y _{1} - y_2 }{x_1 - x_2} }[/tex]
slope
[tex] = \frac{3 - 2}{3 - 0} [/tex]
[tex] = \frac{1}{3} [/tex]
Thus, the equation of the graph is y= ⅓x +2.
The area of a rectangular room is 750 square feet. The width of the room is 5 feet less than the length of the room. Which equations can be used to solve for y, the length of the room? Select three options. y(y + 5) = 750 y2 – 5y = 750 750 – y(y – 5) = 0 y(y – 5) + 750 = 0 (y + 25)(y – 30) = 0
Length be x
width be x-5
So
Area=Length×Breadth
x(x-5)=750Or
If x turned y
y(y-5)=750750-y(y-5)=0Option C
Option A can be true as per commutatI've property
y²-5y=750Option B is true
Answer:
y² - 5y = 750
750 - y(y - 5) = 0
(y + 25)(y - 30) = 0
Step-by-step explanation:
Formula
Area of a rectangle = length × width
Given:
y = length of the room(y - 5) = width of the room750 ft² = area of the roomSubstituting the given values into the formula and rearranging in different way:
Equation 1
⇒ 750 = y(y - 5)
⇒ y(y - 5) = 750
⇒ y² - 5y = 750
Equation 2
⇒ 750 = y(y - 5)
⇒ 750 - y(y - 5) = 0
Equation 3
⇒ 750 = y(y - 5)
⇒ y(y - 5) - 750 = 0
⇒ y² - 5y - 750 = 0
⇒ y² - 30y + 25y - 750 = 0
⇒ y(y - 30) + 25(y - 30) = 0
⇒ (y + 25)(y - 30) = 0
A box of chocolates contains 10 milk chocolates, 8 dark chocolates and 6 white chocolates. Sung randomly chooses a chocolate, eats it, then randomly chooses another. What is the probability Sung chose a milk chololate then a white chocolate
Using it's concept, it is found that there is a 0.1087 = 10.87% probability Sung chose a milk chocolate then a white chocolate.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem, we have that:
Initially, there are 10 + 8 + 6 = 24 chocolates, out of which 10 are milk, hence the probability of eating a milk chocolate first is given by: [tex]\frac{10}{24} = \frac{5}{12}[/tex].Then, there will be 23 chocolates, out of which 6 will be white, hence the probability of eating a white chocolate first is given by: [tex]\frac{6}{23}[/tex].Thus, the probability of milk then white is given by:
[tex]p = \frac{5}{12} \times \frac{6}{23} = \frac{30}{12 \times 23} = 0.1087[/tex]
0.1087 = 10.87% probability Sung chose a milk chocolate then a white chocolate.
