Answer:
I'm pretty sure the peremiter is 466 ft.
Answer:
the 3rd and 5th one
Step-by-step explanation:
We have that
<span>f(x) = x/4 -3
g(x)= 4x</span>²<span>+2x-4
find (f+g)( x)
step 1
adding the two functions together to create a new function.
[x/4 -3]+[4x²+2x-4]
step 2
making everything have a common denominator of 4 we get:
[(x-12+16x²+8x-16)]/4
step3
combine like terms in numerator
(16x²+9x-28)/4-----------> 4x²+(9/4)x-7
the answer is </span>4x²+(9/4)x-7
Answer:
x = -8 ± √62
Step-by-step explanation:
An equation needs an equals sign. I assume the expression equals zero?
x² + 16x + 2 = 0
To complete the square, start by making the leading coefficient 1 (which it already is).
Next, take half of the b coefficient, square it, and add the result to both sides.
(16/2)² = 8² = 64
x² + 16x + 64 + 2 = 64
Factor the perfect square:
(x + 8)² + 2 = 64
Solve for x:
(x + 8)² = 62
x + 8 = ±√62
x = -8 ± √62
2.16 x 10 to the power of -4
