Follow the process of completing the square to solve 2x2 + 8x - 12 = 0. after adding b2 to both sides of the equation in step 4, what is the constant on the right side of the equation? a. -32 b. 112 c. 160

constant = -12

Step-by-step explanation:

Let the given equation be

2x² + 8x - 12 = 0     (1)

Here B² =(2√2)^2 = 8

Add 8 in both sides  of (1)

Step1 :  2x² + 8x  + 4 = 12  + 4

Step 2:  x² + 4x + 4 = 16

step 3 : x² + 4x + 4 - 16 = 0

Step 4:  x² + 4x - 12 = 0  ---(4)

From the (4) we get constant = -12

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
