Answer:
f(a) = 2a^2 + 4a + 5
Step-by-step explanation:
You just need to replace the "x" with the "a".
Answer:
15
Step-by-step explanation:
5+20+15+18+20+19+12+16+10+15=150/10=15
The answer would be c or 35x4 + 17x3-3x2 +41x -8<span />
The prism has 6 faces: 2(length·width), 2(length·heighth), & 2(width·heighth)
2(length · width) = 2(9.8 · 20) = 2(196) = 392 in²
2(length · heighth) = 2(9.8 · 5) = 2(49) = 98 in²
2(width · heighth) = 2(20 · 5) = 2(100) = 200 in²
The sum of the faces is the surface area (S.A.)
392 in² + 98 in² + 200 in² = 690 in²
