Place the indicated product in the proper location on the grid. (a+b-c)(a+b+c)
aliina [53]

Answer:

The required location on the gird is shown below.

Step-by-step explanation:

Consider the provided expression.

We need to place the indicated product in the proper location on the grid.

First open the parenthesis as shown:

(a+b-c)(a+b+c)=a(a+b+c)+b(a+b+c)-c(a+b+c)

(a+b-c)(a+b+c)=a^2+ab+ac+ab+b^2+bc-ac-bc-c^2

Now add the like terms as shown:

(a+b-c)(a+b+c)=a^2+b^2-c^2+2ab

Hence, the required location on the gird is (a+b-c)(a+b+c)=a^2+b^2-c^2+2ab

VERY QUICK HELP!!!! A toy pyramid has the dimensions shown below. The base of the pyramid is an equilateral triangle. What is th
Elanso [62]

Answer: 102cm²

Step-by-step explanation:

Area of base = 6 × 7 ÷ 2 = 21

Area of lateral face = 6 × 9 ÷ 2 = 27

Since all of the sides of the base are equal, we can multiply the area of 1 lateral face by 3 to get the area of all the lateral faces.

27 × 3 = 81.

Now we add up the area of the base and the lateral faces.

21 + 81 = 102cm²

I am not a professional, simply using prior knowledge!

Note- It would mean the world to me if you could mark me brainliest!
