Percent change=change/original times 100

perimiter
if length and width double then the perimiter doubles
because
P=2(L+W)
L=10
W=6
old one
P=2(10+6)
P=2(16)
P=32
new one
20 and 12
P=2(20+12)
P=2(32)
P=64

percent change=change/original times 100
change=64-32=32
original=32
percent change=32/32 times 100=100%



area
old are=legnth tiems wdith =6 times 10=60
nwe one
area=12 times 20=480
change is 240-60=180
percent change=180/60 times 100=3 times 100=300





perimiter is 100% change
area is 300% change

Factor the polynomial completely x4-36​
Olegator [25]

Answer:

The factors of the polynomial are x = ± \sqrt{6}

Step-by-step explanation:

consider x⁴ - 36 = 0

(x² - 6) (x² + 6) = 0

x² = 6 and x² = -6

∴ x =  ±\sqrt{6}

The factors of the polynomial are x = ± \sqrt{6}

6q-7=2q+29 I don't know how to do this, help please.
Tems11 [23]
The first thing you should do is to add -2q on both sides of the equation and then add +7 on both sides so you will have:
6q - 2q = 29 +7 
4q = 36 so q is equal to 36/4 or 9 :)))
i hope this is helpful
have a nice day
