v² - 6su²v - 7s²[tex]u^{4}[/tex]
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor, that is
= v(v + su²) - 7su²(v + su²) ← distribute both parenthesis
= v² + su²v - 7su²v - 7s²[tex]u^{4}[/tex] ← collect like terms

Answer:
71 degrees
Step-by-step explanation:
All angles in a triangle must add up to 180 degrees. If we take that total 180 and subtract 38, we get 142 degrees. If we divide that by two, because the angles are the same, we get 71 degrees. Therefore x=71
2) Solve this system of linear equations by elimination.
2x+4y=-4
3x=-5y-3
*x=5,y=-2
*x=4,y=-3
*x=-5,y=2
*x=4,y=3
please answer step by step
Answer: x=4 and y=-3
Step-by-step explanation:
To use elimination to solve system of equations, you want to make sure the equations are first in standard form.
2x+4y=-4
3x+5y=-3
We want to make sure either the x or the y are equal so we can eliminate them. Let's eliminate x.
2x+4y=-4 [multiply equation by 3]
3x+5y=-3 [multiply equation by 2]
6x+12y=-12
6x+10y=-6
We can now subtract the equations.
2y=-6 [divide both sides by 2]
y=-3
Now that we know y=-3, we can plug it into an equation to solve for x.
2x+4y=-4 [plug in y=-3]
2x+4(-3)=-4 [multiply]
2x-12=-4 [add both sides by 12]
2x=8 [divide both sides by 2]
x=4
The final answer is x=4 and y=-3.

Answer:
[tex]\displaystyle r=\sqrt[3]{\frac{3V}{4\pi}}[/tex]
The last option matches the correct solution
Step-by-step explanation:
Equation Solving
We have the following equation:
[tex]\displaystyle V=\frac{4}{3}\pi r^3[/tex]
And it's required to solve it for r.
Solving this equation needs to perform some operations to have the r isolated from any other variables or constants.
It can be done by conveniently operating on both sides as follows:
Eliminate the denominator by multiplying by 3:
[tex]\displaystyle 3V=4\pi r^3[/tex]
Move [tex]4\pi[/tex] to the other side by dividing by [tex]4\pi[/tex]:
[tex]\displaystyle \frac{3V}{4\pi}= r^3[/tex]
Swapping sides to have r at the left side:
[tex]\displaystyle r^3=\frac{3V}{4\pi}[/tex]
Finally, take the cubic root and leave r alone:
[tex]\displaystyle r=\sqrt[3]{\frac{3V}{4\pi}}[/tex]
The last option matches the correct solution

Solve for the missing arc measure, angle measure, or variable.
m < BOC = _____ degrees.
Please help! I’ll give brainliest!!
Answer:
110
Step-by-step explanation:
The answer is 110 degrees. The reason is hard to put into simple language.
If the central angle and the acute angle hitting the circumference share the same end points, then the central angle is double the arc whose vertex is on the circumference.
Read that sentence a couple of times. I don't know how to make it simpler.
The arc angle and the central angle both have B and C as their end points.
The arc angle is on the circumference of the circle. The vertex (A) of BAC is on the circumference. If mine is the only answer, wait a few days before awarding a Brainliest. A thanks will do.
I dont know how to write the question or answers
Answer:
i think i think its B
Step-by-step explanation:
Two rival dry cleaners both advertise their prices. Store A's prices are modeled by the expression 30x - 8, where x is the number of items brought in. Store B's prices are modeled by the expression 6(5x + 3), where x is the number of items brought in. When do the two stores charge the same rate?
Store A's prices are represented by the expression 15x - 2.
Store B's prices are represented by the expression 3(5x + 7).
To find when the 2 stores charge the same rate , we set the expression equal and solve for x
15x - 2 = 3(5x+7)
15x -2 = 15x + 21
Subtract 15x on both sides
-2 = 21
We cannot solve for x
So , the price of two stores never be same
Two stores never charge the same rate

12. The second of three numbers is one less than the first. The third
number is 5 less than twice the second. If the third number exceeds the
first number by 12, find the three
numbers.
Answer:
The three numbers are 19, 18, and 31.
Step-by-step explanation:
The three numbers are x, y, and z.
y=x-1
z=2y-5
z=x+12
2y-5=x+12
2(x-1)-5=x+12
2x-2-5=x+12
x=19
y=18
z=31
The three numbers are 19, 18 and 31
what is Algebra?Algebra is the branch of mathematics that helps in the representation of problems or situations in the form of mathematical expressions.
let the three numbers be x, y, and z.
So, according to question
The second of three numbers is one less than the first,
y = x-1
The third number is 5 less than twice the second,
z=2y-5
also, If the third number exceeds the first number by
12z=x+12
Now, equating the equations
2y-5=x+12
2(x-1)-5=x+12
2x-2-5=x+12
x=19
So, y=18 and z=31.

A metallurgist wants to make 130 grams of an alloy that is to be 20% copper. She has samples that are 14% copper and 22% copper. How many grams of the sample that contains 14% should she use?
Answer:
She should use 32.5 g of the sample that contains 14%
Step-by-step explanation:
Here, we want to know the number of grams of the sample that contains 14% copper that should be used
let the number of grams that contains 14% copper to be used be x
Then the number of grams of 22% will be 130-x
Thus, mathematically;
0.14(x) + 0.22(130-x) = 0.2(130)
0.14x + 28.6 - 0.22x = 26
0.22x - 0.14x = 28.6 - 26
0.08x = 2.6
x = 26/0.08
x = 32.5
