( -x^2 - 4x - 5) + ( -x^2 + 8x + 8)
Take out parentheses:
- x^2 - 4x - 5 - x^2 + 8x + 8
Write in a way so that like terms are grouped together:

Answer:

Step-by-step explanation:
This is cube root (hence the [tex]\sqrt[3]{}[/tex]).
To find the cube root of a number, we are looking for a number that, when multiplied by itself 3 times, equals the number inside the sign.
So:
[tex]3^x = 27[/tex]
We know that [tex]2\cdot 2\cdot 2 = 8[/tex], so this doesn't work.
We also know that [tex]3 \cdot 3 \cdot 3 = 27[/tex], so this works.
Therefore the cube root of 27 is 3.
Hope this helped!
Answer:
the answer is three
Step-by-step explanation:
If you multiply three by itself three times you will get 27.

Answers
Answer:
-10 °C
Step-by-step explanation:
Subtract 90 from 80, since it dropped that much:
80 - 90
= -10
So, the temperature after it fell was -10 °C
Answer: -10 Celcius
Step-by-step explanation:
The tempature was 80 degrees and dropped by ninety, and since it dropped then you must subtract. 80 - 90 is -10 degrees Celcius. The temperature is -10 Celcius.

Point b, o, and y are collinear on by, and bo:oy = 1/3. B is located at (4,-2,) o is located at (5,-2) and Y is located at (x,y) determine the value of y
Answers
Answer:
The value of the y-coordinate is -2
Step-by-step explanation:
Here in this question, we want to use the section formula to determine the y- coordinates of the line that divides the segment in the ratio 1:3 or 1/3
The formula to use to get the coordinates is;
( (mx2 + nx1) /m + n , (my2 + ny1)/( m + n))
So in this case;
m = 1 n = 3
x1 = 4 , x2 = 5
y1 = -2 , y2 = -2
So substituting these values ( we will only make for the y part since we only need to get the y coordinate)
Hence;
[1(-2) + 3(-2)]/(1+3) = (-2-6)/4 = -8/4 = -2

Hi there!

Answer:
[tex]16 + 28 + -42[/tex]
[tex]= 44 - 42[/tex]
[tex]= 2[/tex]
❀Hope this helped you!❀
☽------------❀-------------☾
Answer:
2
Step-by-step explanation:
This is the answer because:
1) First, we have to add 16 and 28 which is 44
16 + 28 = 44
2) Next, we have to add 44 and -42, which will be 2 because whenever we have to add or subtract integers, we are supposed to multiply the signs, and then we have to put the sign of the greater number. In this case, it would be:
44 + (-42) = 44 - 42 = 2

The Segment Addition Postulate involves the addition of two segments with a common endpoint. Which conditions regarding the endpoints must be met? select all that apply.
they are coplanar
one point is between the other two
they are non-coliner
the points are randomly place on the line
they are coliner
Answers
Answer:
they are collinear
one point is between the other two
Step-by-step explanation:
The conditions regarding the endpoints that must be met are;
Option B; One point is between the other two.
Option E; They are colinear.
The segment addition postulate states that if for example we have two points on a given line segment with endpoints, X and Z, then there will be a third point Y that resides on the line segment XZ if and only if the distances between the points meet the requirements of the equation XY + YZ = XZ.Let's look at the options;
Option A; This is not correct because coplanar means in the same plane but what we need is colinear points but coplanar points are not always colinear.Option B; This is correct because as seen above, point Y is between Point X and Z.Option C; This is not correct because they have to be colinear and not non-colinear.Option D; This is not correct because random placement may lead to non conformation with the equality of segments.Option E; This is correct because they have to be on the same line and are colinear.Read more at; https://brainly.com/question/17491162
−16=−4(2x−8) please help
Answers
Answer:
x = 6
Step-by-step explanation:
−16=−4(2x−8)
Let's rearrange so solving would be easier.
-4(2x-8) = -16
Let's open the brackets. Please take note of the signs (+) (-).
(-4 * 2x) + (-4 * -8) = -16
-8x + 32 = -16
Subtract 32 from both sides. Please take note of the signs (+) (-).
-8x + 32 (-32) = -16 (-32)
-8x + 0 = = -48
-8x = -48
Divide both sides by -8.
-8x/-8 = -48/-8
x = 6

Find the area of the rectangle.
2x + 4
4x - 2
Answers
Answer:
8x² + 12x – 8
Step-by-step explanation:
From the question given above, the following were obtained:
Length (L) = 2x + 4
Breadth (B) = 4x – 2
Area (A) =..?
The area of a rectangle is given by:
Area (A) = Length (L) × Breadth (B)
A = L × B
Thus with the above formula, we can obtain the area of the rectangle as follow:
Length (L) = 2x + 4
Breadth (B) = 4x – 2
Area (A) =..?
A = L × B
A = (2x + 4) (4x – 2)
Expand
A = 2x(4x – 2) + 4(4x – 2)
A = 8x² – 4x + 16x – 8
A = 8x² + 12x – 8
Therefore, the area of the rectangle is 8x² + 12x – 8
