what is the first step in solving the quadratic equation  x^2  – 40 = 0? taking the square root of both sides of the equationadding 40 to both sides of the equationsquaring both sides of the equationsubtracting 40 from both sides of the equation

Adding 40 to both sides of the equation.

Step-by-step explanation:

The first step in solving a quadratic equation, is always to work towards getting the variable alone on one side of the equation. In this case, when adding adding 40 to both sides, the left side will become x² and the right side will become 40.

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)
