Simplify 9+(-2) to the third power 1 3 17

1

Step-by-step explanation:

9+ (-2)^3

We need to do exponents first according to PEMDAS

9 + (-8)

Then we add

1

See below in bold.

Step-by-step explanation:

FA, CD and BE are the medians of the triangle.

So AE + EC

that is x = 2x - 4

giving x = 4.

Also  the sides length 10 and 4y-2 are in the ratio 2:1 (property of  intersecting medians).

10 = 2(4y - 2)

8y - 4 = 10

8y = 14

y = 14/8

y = 1.75.
