Can any one help me lease I do not under stand.

svetoff [14.1K]

Answer: the cube root of 512 is 8.

Step-by-step explanation:

First divide 512 and take the least factors as I have shown,

512= 2×2×2×2×2×2×2×2×2

Now, make the triple twins of these factors,

(2×2×2)(2×2×2)(2×2×2)

Now, take one number from each pair and multiply them,

2×2×2=8

Therefore, the answer of the cube root of 512 is 8.

If the quadratic equation x2+18x+74=0 is rewritten in the form (x−p)2=q, what is the value of q?

PilotLPTM [1.2K]

Answer:

C) 7

Step-by-step explanation:

Quadratic equation

The quadratic equation can be written in several ways, one of the most-used is

$ax^2+bx+c=0$

To rewrite the equation in the form

$(x-p)^2=q$

we can complete squares and rearrange the terms as follows. The provided equation is

$x^2+18x+74=0$

The second term can be seen as

$2(x)(9)$

And the first two terms can be visualized as the square of a binomial

$x^2+2(x)(9)+81-81+74=0$

We have added and subtracted 81 to complete the square and not modify the equation. The new form of the equation is

$(x+9)^2-7=0$

Rearranging

$(x+9)^2=7$

Comparing with the general form written above, we find that

$\boxed{q=7}$
