Answer:

Area = 3x^5+3x^4-3x^3-3x^2

Step-by-step explanation:

Area equals length times width

x(x+1) * 3x(x^2-1)

(x^2+x) * (3x^3-3x)

3x^2(x+1)(x^2-1)

3x^5+3x^4-3x^3-3x^2

-12=-2(2-8) <br> Is it true false or an open sentence
MissTica
The statement is false because when you use distributive property, you get -12=-4+16 and when you add 16 to -4, you'll get 12, not -12, making the statement false.

PLEASE HELP ME WITH MY MATH
Alina [70]

Answer:

Step-by-step explanation:

1)

y is 3 times more than x.

X=0 Y=0  3x0=0

X=1  Y=3

X=2 Y=6

X=3 Y=9

X=4 Y=12

Then just plot it as co-ordinates (x,y)

2)

Y is 1/4 of x. Divide by 4

X=0 Y=0

X=4 Y=1

X=8 Y=2

X=12 Y=3

X=16 Y=4

Then just plot it as co-ordinates (x,y)
