which of the following polynomials is in standard form? apex
a) f(x)= -3x^4+6x^2+7x-1
b) f(x)= -3x^4-1+6x^2+7x
c) f(x)= -3x^4+6x2-1+7x
d) f(x)= 7x+6x^2-1-3x^4

unless if u could do my questions, if not i wouldn't want to

step-by-step explanation:

1. sometimes

2. never true

3. sometimes

step-by-step explanation:

these are pretty self explanatory if you know what supp right and com angles are

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .
