Answer:
Step-by-step explanation:
12n2+48n=−n3−64
Step 1: Subtract -n^3-64 from both sides.
12n2+48n−(−n3−64)=−n3−64−(−n3−64)
n3+12n2+48n+64=0
Step 2: Factor left side of equation.
(n+4)(n+4)(n+4)=0
Step 3: Set factors equal to 0.
n+4=0
n=−4
Answer:
976 square cm
Step-by-step explanation:
Area of one 2d triangle face: (24*14)/2=168 square cm
Area of both 2d triangles faces: 168 + 168 =336 square cm
Area of one side: 25*10=250 square cm
Area of both sides: 250+250=500
Area of base: 14*10=140 (since it's a triangular prism, there's only one base)
Surface Area: 336+500+140=976 square cm
Hope this helps! :)
