From their sum, the numbers are ' x ' and ' 8 - x ' .
From their product, x(8 - x) = 80 .
When you massage and manipulate this equation into the standard
quadratic form, you have
x² - 8x + 80 = 0 .
Applying the quadratic formula to tease out the solutions of this equation,
we find that they are
<em> x = 4 + 64 i</em>
and
<em> x = 4 - 64 i</em>
Answer: 10pi
Step-by-step explanation:
C = 2(pi)r
r = 5
2*(pi)*5 = C
10pi = C is the exact answer
If we make 3.14 for the pi substitution, then:
2*3.14*5=C
31.5 = C
Answer:
why 100 when you can have 1000

Answer:
20 +4√2
Step-by-step explanation:
Find the total area the regular pyramid = A + 1/2ps
A is the Base area
p is the perimeter of the base
s is slant height
A = 1/2 * 4 * 4
A = 16/2
A = 8
p = 4 + 4 + (√4^2+4^2)
p = 8 + √32
p = 8 + 4√2
s = 4
Substitute
TSA = 8 + 8 + 4√2 + 4
TSA = 20 +4√2
Hence the total surface area is 20 +4√2
First, turn the fraction into a decimal.
9.75
Second, multiply by 100%.
9.75 * 100% = 975%
Best of Luck!
