3 0

Answer:

9) 5y

10) 10 x² - 4

11) 2a ∧5 + 5b

12) 8m +4n + 2

Step-by-step explanation:

9) 8 y - 3 y = 5y

10) 6x² + 4 (x²-1) = 6x²+ 4x²-4 = 10x²-4

11) 4a∧5 - 2a∧5 +4b + b = 2a∧5 +5b

12) 8m +14-12+4n = 8m+4n+2

What is GE ?<br> Enter your answer in the box.
Flura [38]

The length of GE is 10 units

Explanation:

Given that the length of XY = 5 units and YZ = 4.6 units

<u>The length of GE:</u>

We need to determine the length of GE

From the figure, we can see that ZY bisects GE and XY bisects EF.

The lines ZY and XY both bisect GF.

The midpoint theorem states that "the line segment connecting the midpoints of  two sides of a triangle is parallel to the third side and is congruent to one half of the third side".

Since, we have,

EX = XF and X is the midpoint of EF

GY = YF and Y is the midpoint of GF

Since, XY is the line segment that connects the midpoints of the two sides of the triangle.

Applying the midpoint theorem, we have,

GE = 2XY

GE = 2(5)=10 \ units

Thus, the length of GE is 10 units.

How do you factor n^3-2n^2 ?
antoniya [11.8K]
Factor out common numbers or variables when you can.

To make this the most simplified factor, factor out n², as it is the least factor both have.

n³/n² = n
-2n²/n² = -2

n - 2 is your new answer


hope this helps
