sqrt(18a)
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
The factor that can be put back into the square root is 9.
√(2 x 9 x a) = √(18a) = 3√(2a)
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
3√(2a)
A factor that can be put back into the square root is 9.
√(2 x 9 x a) = √(18a) = 3√(2a)
3² = 9
Thus,
The factor that can be put back into the square root is 9.
√(2 x 9 x a) = √(18a) = 3√(2a)

uppose a normal distribution has a mean of 16 and a standard deviation of 4. A value of 26 is how many standard deviations away from the mean
Answer:
2.5 s. d.
Step-by-step explanation:
Use the formula for calculating z scores:
26 - 16
z = ------------- = 10/4 = 2.5

Here the value 26 is 2.5 standard deviations above the mean (16).
Paul was thinking of a number.Paul doubles it and gets a answer of 13.1.What was the orginal number?
Answer:
See below:
Step-by-step explanation:
So first, Paul has a number that he got before he multiplied it, we can call that [tex]p[/tex], and for his answer after doubling it. we'll call it [tex]n[/tex].
So with this information, we know that [tex]n=13.1[/tex] so we can use that to make an equation.
[tex]p*2=n\\p*2=13.1[/tex]
We can solve it by first dividing on both sides and getting our answer.
[tex]p=\frac{13.1}{2} \\p=6.55[/tex]
Cheers! We get our final answer of 6.55.

The black graph is the graph of
y = f(x). Choose the equation for the
red graph.
a. y = f(x + 3)
b. y = f(x – 3)
C. y + 3 = f(x)
d. y - 3 = f(x)
Answer:
C
Step-by-step explanation:
When
f(x+3) would indicate a Shift 3 units to the left
f(x-3) indicates a Shift 3 units to the right
y+3=f(x) indicates a Shift 3 units up
y-3=f(x) indicates a Shift 3 units down
Because the graph is shifted 3 units up, it would be y+3=f(x), which is option C
18-3(8c+4)=-6(4c-1) show your work
Answer:
No solution
Step-by-step explanation:
Solve:
18 + -3(8c + 4) = -6(4c + -1)
Reorder the terms:
18 + -3(4 + 8c) = -6(4c + -1)
18 + (4 * -3 + 8c * -3) = -6(4c + -1)
18 + (-12 + -24c) = -6(4c + -1)
Combine like terms: 18 + -12 = 6
6 + -24c = -6(4c + -1)
Reorder the terms:
6 + -24c = -6(-1 + 4c)
6 + -24c = (-1 * -6 + 4c * -6)
6 + -24c = (6 + -24c)
Add '-6' to each side of the equation.
6 + -6 + -24c = 6 + -6 + -24c
Combine like terms: 6 + -6 = 0
0 + -24c = 6 + -6 + -24c
-24c = 6 + -6 + -24c
Combine like terms: 6 + -6 = 0
-24c = 0 + -24c
-24c = -24c
Add '24c' to each side of the equation.
-24c + 24c = -24c + 24c
Combine like terms: -24c + 24c = 0
0 = -24c + 24c
Combine like terms: -24c + 24c = 0
0 = 0
Solving
0 = 0
No Solution

Well, here we look at the frequency to determine probability. As a dice has 3 even and odd numbers, the probability shall be gotten by dividing the total number of frequencies for even numbers (2,4,6) by the total number of trials.
i.e (10+10+9)/50
so the probability is 29/50 or 0.58 or 58%
Since the probability of getting even numbers is 0.58 and since the total probability is always 1, we can clearly see that the probability of one rolling an even number as per the sample is higher than that of rolling an odd number.

problem 6) x = 5problem 7) x = 5problem 8) x = 4problem 9) x = 6================================================
Explanation:
The angles with the similar arc markers are congruent angles. This is only when we consider any particular triangle isolated from the others.
Since we have 2 congruent angles, the triangles are considered isosceles. The congruent sides are opposite the congruent angles.
So we'll set the congruent side expressions equal to one another and solve for x. We ignore the side that isn't opposite one of the congruent angles. This applies to all four problems.
---------------------------
Work Shown for Problem 6:
3x = x+10
3x-x = 10
2x = 10
x = 10/2
x = 5
---------------------------
Work Shown for Problem 7:
x = 10-x
x+x = 10
2x = 10
x = 10/2
x = 5
---------------------------
Work Shown for Problem 8:
4x-12 = x
4x-x = 12
3x = 12
x = 12/3
x = 4
---------------------------
Work Shown for Problem 9:
2(x+3) = 18
2x+6 = 18
2x = 18-6
2x = 12
x = 12/2
x = 6
Or you can solve it like this
2(x+3) = 18
x+3 = 18/2
x+3 = 9
x = 9-3
x = 6
The figure below shows a circular fountain in a park with a garden to be planted with flowers. The parks department wants to plant groups of 2 flowers in the garden per square foot. Garden 3 feet 18 feet Fountain Which is closest to the number of flowers needed to plant in the garden?
A 71 flowers
B. 141 flowers
C 156 flowers
D 255 flowers
E 284 flowers
Answer: The answer is 284.
Step-by-step explanation:
The area of the garden is an annulus whose,
Outer diameter = 18 ft
Inner diameter = 18 ft - 2*3ft = 12 ft
Therefore,
Outer radius = 18/2 = 9 ft
Inner radius = 12/2 = 6 ft
Area of garden = Area of annulus
Area of garden = π*(9 ft)2 - π * (6 ft)2
Area of garden = 142
Given:
2 flowers are planted per square foot.
Therefore for 142 ft2,
Number of flowers required = 2*142 = 284
The answer is 284.

Write an equation in standard form of the line that contains the point (-1,4) and is parallel to (has the same slope as) the line y=2x-7
The equation of the line in standard form is
Answer:
slope of line AB = 5
Let the required line be 'l'.
since AB is parallel to 'l'.
so slope of 'l' = slope of AB = 5.
So, the required equation of line which passes through (4,5) and having slope 5 is given by
y - 5 = 5(x - 4).........[using slope point form]
y = 5x - 20 + 5
y = 5x - 15.

How to find unique prime factorization of 10 factorial.
Evaluate the expression m+np−q if m=1/15, n=−1/3, p=−0.4, and q=2 1/3. Express your answer as a decimal. Use bar notation if necessary.
Answer:
-2.4, or -72/30 or -2 4/10
Step-by-step explanation:
m + np - q
m = 1/15
n = -1/3
p = -0.4
q = 2 1/3
1/15 + (1/3)(-0.4) - 2 1/3
1/15 + (-4/30) - 2 1/3
2/30 - 4/30 - 70/30
-2/30 - 70/30 = -72/30
-72/30 = -2.4

work out the m and c for the line 3y+2x=-1
Answer:
m = -2/3 and b = -1/3
Step-by-step explanation:
Write the equation of this line in slope-intercept form. Then m = slope and b = y-intercept and the basic equation is y = mx + b.
Solving 3y+2x=-1 for y, we get 3y = -2x - 1, or y = (-2/3)x - 1/3
Here we can easily see that m = -2/3 and b = -1/3.
