Answer:
B
Step-by-step explanation:
we know the thickness is x, so the sides are 3+2x and 4+2x
then we use foil:
(3+2x)(4+2x)=12+6x+8x+4x^2=4x^2+14x+12
we know the area is 15
4x^2+14x+12=15
4x^2+14x-3=0
So it is B
A
what is your question there is no equation
−7k^4−11k^2+6
−4k^4+14+3k^2−3k^4−14k^2−8
(−4k^4+−3k^4)+(3k^2+−14k^2)+(14+−8)
...
A=Both distributions are nearly symmetric
