Which numbers are solutions to the equation 30=x2
? Select all that apply.
x=15
x is equal to 15
x=30−−√
x is equal to square root of 30
x=900
x is equal to 900
x=−15
x is equal to negative 15
x=−30−−√
x is equal to negative square root of 30
x=−900
Answer:
x = +√30
Step-by-step explanation:
Please write 30 = x squared as 30 = x^2.
If x^2 = 30, there are two solutions: x = +√30 and x = -√30.
Several possible answers are given. x=30−−√ is closest to the correct one, but must be written as x = √30. Please ask someone how to find the "√" operator in Brainly. Or, just write "sqrt( )" instead.
For which of the following is x = -5 a solution? Select all that apply.
Answer:
Options 2, 3, 4, 5 are the solutions.
Step-by-step explanation:
Option 1).
x + 10 = -5
x = -10 - 5
x = -15
Therefore, x = -5 is not the solution.
Option 2).
-x² + 50 = 25
-x² = 25 - 50
-x² = -25
x² = 25
x = ±5
Therefore, x = -5 is a solution
Option (3)
|2x| = 10
2x = ± 10
x = ± 5
Therefore, x = -5 is a solution.
Option (4)
x < 0
Since, -5 < 0
Therefore, x = -5 is a solution.
Option (5)
2x < 10
x < 5
Since, -5 < 5
Therefore, x = -5 is a solution.
Options 2, 3, 4, 5 are the solutions.
PLEASE HELP Write a one chunk paragraph explaining the steps to solve for the equation 3(2x+1)=4x+5
Answer:
x = 1
Step-by-step explanation:
First perform the indicated multiplication:
3(2x+1)=4x+5 becomes 6x + 3 = 4x + 5.
Consolidate like terms: 2x = 2
Solve for x: x = 1
Answer:
Step-by-step explanation:
To solve the equation, first you would multiply 3 times 2x and 3 times 1. Then, you would write 6x plus 3 on the right side of the equation. Then, you would subtract 3 from both sides of the equation. You then will have 6x=4x+2. Lastly, you would get an answer of x=1

Please answer this question.
See picture attached.
Just question C please.
Answer:
Diagram B
Step-by-step explanation:
Diagram A makes sense to have a line of best fit because there is a common amount of data for where the next points probably will be. The points are close to the line of best fit, and there are pretty much an even amount of points on each side of the line. So, Diagram A’s line of best fit makes sense.
Diagram C makes sense to have a line of best fit because about the line, all the points are right next to it, and the line of best fit gives a nice representation of the data. So, Diagram C’s line of best fit makes sense.
For Diagram B, all of the points all scattered across the graph and none of them are close to the line of best fit, and a line a best fit is usually made to make an estimat of where the data will be, but for example, the point (20,90) is nowhere near the line of best fit. So, Diagram B’s line of best fit should not have been drawn.

Answer:
9a^4b^10 ( 4 - 9a^12b^20)
Step-by-step explanation:
The greatest common factor of the two terms is 9a^4b^10
You can now remove the greatest common factor outside the brackets.
Inside the brackets, you place the value obtained by dividing 36a^4b^10- 81a^16b^20 by 9a^4b^10
That is = 4 - 9a^12b^20
Please note that the laws of indices i used for the above division is: n^a divided by n^b = n^(a-b)
Now, the factorised answer for your question = 9a^4b^10 ( 4 - 9a^12b^20)
Hope thos helps

Volume= 360 feet³
Step-by-step explanation:
We have two shapes, a triangular prism and a rectangular prism.
Rectangular Prism: [tex]w=6, h=2, l=8, V=lwh[/tex]
So, the volume is 6×2×8=96 feet³
Triangular Prism: [tex]h=5.5-2=3.5, w=6, l=8, V=\frac{1}{2}lwh[/tex]
So, the volume is (5.5×6)÷2 ×8= 33×8=264 feet³
We have to combine the two volumes to find the volume of the whole shape. 96+264=360. So, the volume of the whole shape is 360 feet³

Find two numbers that multiply to 16 and also add to -8
Answer:
-4,-4
Step-by-step explanation:
let the numbers be x and y.
x+y=-8
y=-x-8
xy=16
x(-x-8)=16
-x²-8x=16
x²+8x+16=0
x²+4x+4x+16=0
x(x+4)+4(x+4)=0
(x+4)(x+4)=0
x=-4,-4
