-10/5+2(7-9)^2
Oksana_A [137]
Answer: -4

Reasoning: so first you need to subtract the 7 from the 9 to get -2. Then you square it to get 4 because a negative 2 times -2 is 4. Then you multiply the 4 by the 2 to get 8. You can simplify the -10/5 to -1/2 and multiply that by the 8 to get -8/2 which simplified out to -4.


I hope that helps.

Gekata [30.6K]

Answer:

The surface area of the gift box that Kira decorates is 253.5\ in^{2}

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

A cube has six square faces

The surface area of a cube is equal to the area of the six squares faces

SA=6b^{2}

where

b is the length side of a cube

In this problem we have

b=6.5\ in

substitute

SA=6(6.5)^{2}

SA=253.5\ in^{2}
