what is the first step in finding the consecutive whole numbers between which square root of 845 is located
marysya [2.9K]

Answer:

The first step to do is trying to find the closest perfect square less than 845, and the closest perfect square more than 845.

In this case 29^2 (841) is the closest perfect square less than 845, and 30^2 (900) is the closet perfect square more than 845.

In conclusion we will say that 29 < √ 845 < 30.

Hope it helps you.

Prove algebraically that (m + 2)2 – m 2 – 12 is always a multiple of 4
Julli [10]

Answer:

(m + 2)^{2} - m^{2}  - 12 = 4(m - 2)

Step-by-step explanation:

Step 1:

Write the expression

(m+2)^{2} - m^{2}  - 12

Step 2: Expand (m + 2)^{2}

(m+2)^{2} - m^{2} - 12\\(m+2)(m+2) - m^{2}  - 12\\m^{2} + 2m + 2m + 4 - m^{2}  - 12

Step 3: Collect similar terms

m^{2}  - m^{2}  + 4m + 4 - 12\\4m - 8

Step 4: Factor 4 out of the expression to prove that the expression is a multiple of 4.

Therefore\\4m - 8 = 4(m - 2)\\Hence,\\(m+2)^{2}  - m^{2} -  12 is a multiply of 4 because the expression is equal to 4(m-2)
