HELP ASAP FOR BRAINLIEST!!
Tell whether the expression in the pair is equivalent.
(the asterisks '*' stand for multiplication)
vwx * yz and v * w * zxy
Answer:
Yes
Step-by-step explanation:
Let's say each letter was a different number. When it comes to multiplication the order doesn't matter, plus the numbers that are together are just number multiplied.
Example:
(1)(2)(3)*(4)(10)Equals 240
If you switch those around, no matter what it will equal 240
Answer: They are equivalent
Both expressions have one copy of v, w, x, y, and z in some order all being multiplied. We can multiply any two numbers in any order we want
a*b = b*a
For example,
2*3 = 3*2
Since both equal 6.
We can extend this idea out to more than two things being multiplied and the order still doesn't matter. This idea is the commutative property of multiplication.
Solve the equation.

z/7−9=2
Two-Step Equations and Properties of Equality
Answer:
z = 77
Step-by-step explanation:
Given
[tex]\frac{z}{7}[/tex] - 9 = 2 ( add 9 to both sides )
[tex]\frac{z}{7}[/tex] = 11 ( multiply both sides by 7 to clear the fraction )
z = 77
5-20 Find f'(x).
5. f(x) = (3x² +6) (2x - 3)
Answer:
f'(x) = 18x² - 18x + 12
Step-by-step explanation:
Differentiate using the power rule
[tex]\frac{d}{dx}[/tex] (a[tex]x^{n}[/tex] ) = na[tex]x^{n-1}[/tex]
Given
f(x) = (3x² + 6)(2x - 3) ← expand factors using FOIL
= 6x³ - 9x² + 12x - 18 , then
f'(x) = 3.6x² - 2.9x + 12
= 18x² - 18x + 12

An arithmetic sequence is given below.
17, 22, 27, 32,
Write an explicit formula for the n
th
term an
a
n
0 0
Х
?
Answer:
n5 + 17
Step-by-step explanation:
They're asking for a pattern.
17 + 5 = 22
22 + 5 = 27
27 + 5 = 32
So it starts at 17 and increases by five each time.
The nth term increases by 5 each time and starts at 17. That means the nth term is multiplied by 5 each time, but you have to add 17 because that's where the pattern starts.
n5 + 17

Denise wants to cover a 21.75 square foot wall with weathered wood. If each box of weathered wood contains 1.5 square feet of wood, how many boxes of weathered wood does she need?
Answer: 15 boxes
Step-by-step explanation:
From the question, we are informed that Denise wants to cover a 21.75 square foot wall with weathered wood and that each box of weathered wood contains 1.5 square feet of wood.
The number of boxes of weathered wood that she need will be calculated by dividing 21.75 square feet by 1.5 square feet. This will be:
= 21.75/1.5
= 14.5
= 15 boxes approximately

Answer:
The initial height would be the intersection between the line and the y-axis, or the y-intersect
Step-by-step explanation:
Initial height means the height before any time has passed, so the x-axis representing time must have a value of 0. Because of this the initial height is the y-intercept.
If I have a circle that is 12 in in diameter and it's cold and a half and then folded in half again what is the area of the resulting shape and what is how do I write out the equation
Answer:
A= πr^2/4Step-by-step explanation:
Step one:
given data
diameter of circle= 12 in
the radius is r=d/2=6in
the area of the circle is
A=πr^2
A=3.142*6^2
A=3.142*36
A=113.1in^2
If the circle is folded in half, the area will be A/2= 113.1/2= 56.55in^2
In the corresponding shape is folded again the area is A/4= 28.3in^2
The expression for the last shape is
A= πr^2/4

Since the box represents a proportional relationship, the empty box would be = 22.
What is a proportional relationship between two variables?When proportional relationship exists between two variables, it means that a particular value would be times with one variable to give the next compared variable.
For example, using the figures given above;
8 pages of notes = 16hours
1 page = 16/8 = 2 hours
Therefore, each page should be times by two to give the number of hours.

Answer:
15x, 19x, 26x, and 3x
Step-by-step explanation:
To figure this out, we just need to figure out which sort of value can be combined. Every choice except 49 has a variable attached. The different variables are a, y, x, h, and g. There is only one of each variable except for x. So, you would combine each like term with x as an variable.

Your friend says the solution to 6x + 19x - 3 = 5(5x + 6) is x = 33. Solve 6x + 19x-3 = 5(5x + 6). What was your friend's likely error?
Answer: Forgot to divide at the end
Step-by-step explanation:
To figure out your friend's error, solve the equation yourself.
Distribute the 5 to get 25x+30Combine like terms in the first equation toget 25x-3=25x+30Add 3 to the other side.When we do this, we realize adding 3 would make it 33. This shows that the friend likely forgot to divide by 25 to completely isolate x, and stopped at that step.
