Step-by-step explanation:
An area of a rectangle is length times width or l*w=a
Answer: x=−5 or x=5
Step-by-step explanation:
−3x4+27x2+1200=0
Step 1: Factor left side of equation.
−3(x2+16)(x+5)(x−5)=0
Step 2: Set factors equal to 0.
x2+16=0 or x+5=0 or x−5=0
x=−5 or x=5
X=37/5
or 7.4 in decimal form
It can be x = 3 and x = -15
