I'll be sure to give out a Brainliest!! Solve x^2-6x=-5 by completing the square. Show all work for the steps below. (a)For x^2-6x+c=-5+c, what value of c is used to complete the square? (b)Substitute the value for c in Part 2(a). Then complete the square to rewrite the equation as the square of a binomial. (c)Solve for x.

(x - 3)power of 2- 4

Step-by-step explanation: Also I'm only in Middle school so i can't help much. However, with my knowledge i could answer.

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
