Given (x – 7)2 = 36, select the values of x.
Answers
2(x-7)=36
Divide both sides by two
X-7= 36/2
Simplify 36/2 to 18
X-7=18
Add 7 to both sides
X=18+7
Simplify 18+7 to 25
X = 25
The values of the variable "x" which satisfy the equation (x – 7)² = 36 are x = 13 and x = 1.
To find the values of x in the expression (x - 7)² = 36, we need to solve for x using the given equation.
We Expand the square of the binomial: (x - 7)² as x² - 14x + 49,
Now, We Set up the equation as : x² - 14x + 49 = 36,
Next, We Subtract 36 from both sides: x² - 14x + 13 = 0,
Factoring the quadratic equation: (x - 13)(x - 1) = 0,
At last, Applying the zero-product property: x - 13 = 0 or x - 1 = 0,
Solving for x, We get : x = 13 or x = 1.
Therefore, The required values of "x" are x = 13 and x = 1.

A. 11p^13
B. 10m^15
Answer:
11p^(13)
10m^(15)
Step-by-step explanation:
11×11=121 so sqrt(121)=11
Since 26/2=13, then p^(13)×p^(13)=p^(26). This implies sqrt(p^26)=p^13.
sqrt(121p^26)=11p^(13)
In short, you just find sqrt of 121 since 121 is a perfect square and then do p^(26/2) since 26 is even and be done.

Sqrt(100)=10 and m^(30/2)=m^(15).

equation of the parabola in vertex form that passes through (4,-7) and has a vertex of (1,-6)
Answers
[tex]y = -\frac{1}{9}(x - 1)^2 - 6[/tex]
Step-by-step explanation:
The vertex form of the equation for a parabola is given by
[tex]y = a(x - h)^2 + k[/tex]
where (h, k) are the coordinates of the parabola's vertex. Since the vertex is at (1, -6), we can write the equation as
[tex]y = a(x - 1)^2 - 6[/tex]
Also, since the parabola passes through (4, -7), we can use this to find the value for a:
[tex]-7 = a(4 - 1)^2 - 6 \Rightarrow -7 = 9a - 6[/tex]
or
[tex]a = -\frac{1}{9}[/tex]
Therefore, the equation of the parabola is
[tex]y = -\frac{1}{9}(x - 1)^2 - 6[/tex]

A rectangle prism has dimensions of 2 cm x 2 cm x 5 cm what is its surface area explain your reasoning
Answers
The volume of a rectangle prism is 20 cm³
A rectangular prism is a three-dimensional shape with six faces and twelve sides.
Volume of a rectangle prism = length x width x height
2 x 2 x 5 = 20 cm³
Surface area of a rectangle prism = 2 ( lw + wh + lh)
Where:
l = length
w = width
h = height
Surface area = 2 x [ (2 + 2) + (2 x 5) + (2 x5) ]
=2 x (4 + 10 + 10)
= 2 x (24)
= 48 cm²

ReWrite 2/3 and 3/4 with a common denominator
Answers
Answer:
8/12 and 9/12
Step-by-step explanation:
2/3 = 8/12 and 3/4 = 9/12
To get two fractions with common denominators you can find the least common multiple of the denominators or you can multiply 2/3 x 4 and 3/4 x 3
The lowest common denominator between 4 and 3 is 12
To get from 4 to twelve we multiplied by 3. Whatever you do to the bottom you do to the top. The top number is 3.
3 x 3 = 9
So your new fraction is 9/12. If you simply this you get 3/4 so this checks out ✔️
Now we need to do the other fraction
To get to from 3 to twelve we multiply by 4
3 x 4 = 12
Whatever you do to the bottom you have to do it the same to the top
2 x 4 = 8
Now you get 8/12. 8/12 simplified is 2/3 so this Plato’s checks out ✔️

Noah’s remote control car moved 12 feet in 6 seconds. Which graph has a slope that best represents Noah’s car’s average rate of speed?
Answers
We want to find a graph that represents Noah's average speed.
We define the average speed as the quotient between the distance moved and the time it takes to move that distance, then in this case we will have:
s = 12ft/6s = 2ft/s
Then we can define a linear equation:
y = (2ft/s)*x
As the distance that Noah travels in x seconds.
The graph of the given linear function can be seen below, and that is the graph with the slope that best represents Noah's average speed.

y+2z=2
z=-1
Since z = -1, substitute into the second equation
y + 2(-1)=2
y -2 =2
y = 2+2
y=4
We can substitute into the first equation
x+2(4) -5(-1) =10
x+8+5=10
x+13 = 10
