Answer:

15\sqrt{2}

Step-by-step explanation:

The formula we can use is

d=\sqrt{2} *a

Where d is the length of the diagonal and a is the length of the side of the square

Since, the floppies are in square shape and side length is 15, so a = 15

We simply put it into the formula and get length of diagonal.

d=\sqrt{2} *a\\d=\sqrt{2} *15\\d=15\sqrt{2}

Hence, diagonal length is  15\sqrt{2}

How to find all real solutions

\bf \sqrt{\sqrt{x-5}+x}=5\leftarrow \textit{squaring both sides}
\\\\
\sqrt{x-5}+x=25\implies \sqrt{x-5}=25-x\leftarrow \textit{squaring both sides}
\\\\
x-5=(25-x)^2\implies x-5=625-50x+x^2
\\\\
0=x^2-51x+630\implies 0=(x-30)(x-21)

and surely you'd know what the roots are

PLEASE HELP. WILL GIVE BRAINIEST AND 60 POINTS if you show work so I can understand these.
Greeley [361]

Answer:

In #1, the slope of the line is 3

Step-by-step explanation:

To find the slope of any line, you need to use the points in the slope formula.

m(slope) = (y2 - y1)/(x2 - x1)

m = (5 - 2)/(0 - -1)

m = 3/1

m = 3

This means the slope is equal to 3.

Find the greatest common factor of these three expressions.
leva [86]
6x

42/6 = 7 (valid), 18/6 = 3 (valid), 12/6 = 2 (valid)

7, 8, 9, 10, and 11 are all not divisible by 12, and 12 is not divisible by 18, so 6 is the highest number.

Also, each number has at least one x, so you can take one out.

Remaining=
6x (7 + 3x^2 + 2x^3)
