1. AB/EF = P(ABCD)/P(EFGH)
4/5=16/P(EFGH)
P(EFGH)=5*16/4=5*4=20

2. V(old)=lwh =
V(new)=2*l*2*w*2*h =2³(lwh)=2³*V(old)= 8*3600=28800

3. A(old)=ab
A(new)=5a*5b=25ab=25A(old)
new area will be 25 times larger

If you graph the line x=-6 what type of slope would it have?

Hitman42 [59]

Answer:

undefined

Step-by-step explanation:

x=-6 is a vertical line at x=-6.

Any vertical line has an undefined slope.

Let's pick two points on x=-6– (-6,1) and (-6,0)

(1-0)/(-6-(-6))=1/-6+6=1/0

Because you cannot divide by 0, a vetical line has an undefined slope.

Please help me with pythagoras.

lana [24]

Answer:

(q)

$cb \: = \sqrt{4 {}^{2} + {3}^{2} }$

$cb = 5$

$q = \sqrt{ {13}^{2} - {5}^{2} }$

$q = 12$

(r)

$cb = \sqrt{ {13}^{2} - {5}^{2} }$

$cb = 12$

$r = \sqrt{12 {}^{2} - 5 {}^{2} }$

$r = \sqrt{119}$

$r = 10.91$

(s)

$ab = \sqrt{20 {}^{2} - 16 {}^{2} }$

$ab = 12$

$s = \sqrt{12 {}^{2} + 8 {}^{2} }$

$s = 4 \sqrt{13}$

$s = 14.42$

How many solutions y=x^2-10x+25

MrRissso [65]

<h2>There are infinite solution of y.</h2>

Step-by-step explanation:

Given,

y = $x^2$ - 10x + 25

To find, the total number of solutions = ?

∴ y = $x^2$ - 10x + 25

⇒ y = $x^2$ - 2(x)(5) + $5^2$

⇒ y = $(x-5)^{2}$

There are infinite solution of y.

Thus, there are infinite solution of y.
