Please answer asap this person made a mistake what is the error and correct solution to this problem

Answer:

Step-by-step explanation:

Hello, please consider the following.

$(4+x)^2=4^2+2\cdot 4\cdot x+x^2=16+\boxed{8}x+x^2\\\\\text{ ... and not ...}\\\\16+\boxed{4}x+x^2$

So the correct equation becomes.

$x^2+64=16+8x+x^2\\\\8x=64-16=48\\\\\text{ we divide by 8 both sides of the equation.}\\\\x=\dfrac{45}{8}=6$

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

Meredith read 21 out of 40 chapters of her library book What decimal represents the part of the chapters she has NOT yet read?

DerKrebs [107]

If she read 21/40, this means that she hasn’t read 19 of the 40 chapters.

You can divide 19/40 to get the decimal
19/40=0.475

Hope this helps!! :)

Find scale factor, solve for x, and solve for y.

snow_tiger [21]

Answer:

Part 1) The scale factor is 3

Part 2) The value of x is 36 in

Part 3) The value of y is 26 in

Step-by-step explanation:

step 1

Find the scale factor

we know that

If two figures are similar then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

In this problem

Let

z-----> the scale factor

$z=(10+5)/5=3$

step 2

Find the value of x

To find the value of x, multiply the length of 12 by the scale factor

$x=(12)(3)=36\ in$

step 3

Find the value of y

we know that

$(13)(3)=13+y$

$y=39-13=26\ in$
