I believe the answer is cubic centimeter
100% because

is 6 and

is 9 meaning that the sum will come up at 6 or 9 also meaning that its 100%
Answer:
y=8(x+1)²-2
Step-by-step explanation:
Completing the square is a method of factorising. x²+bx+c=0 becomes x²+bx+(
b)²-(
b)²+c=0. This then gets converted to make an equation of (x+
b)²+(-(
b)²+c)=0.
Vertex form is y=a(x-h)²+k.
8x²+16x+6=0 must first be divided by 8 to 8(x²+2x+
)=0 (as there cannot be a coefficient for x²).
This will become 8(x²+2x+
²-
²+
)=0.
From there, using the method above, we can convert it to 8[(x+1)²-1+
]=0.
Solving this gets 8[(x+1)²-
]=0.
With 8 as a, 1 as -h, and 8×-
(-2) as k, we can input this into vertex format to get the result of y=8(x+1)²-2.
**This equation involves completing the square and vertex form, which you may wish to revise. I'm always happy to help!
Answer:
175.415
Step-by-step explanation:
surface area of square pyramid is given by:
Area= s^2 + 2(s)(l)
where s is the base and l is the slant height
in given problem, slant height l is not given, so by using Pythagoras theorem finding l:
c^2= a^2 + b^2
= 8^2 + 4^2
= 48.49
c = 6.96348
Now putting values of s=8 and l= 6.96 in first formula
Area= 8^2 + 2(8)(6.96)
= 64 + 111.41
= 175.415
