Answer:
Corp A. 320,000
Corp B. 40,000
Corp C. 430,000
Corp C owns the most land, Corp A owns 8 times more land.
Explanation:
3.2.• 10^5 = 3.2 • 100,000 = 320,000
4 • 10^4 = 4 • 10,000 = 40,000
4.3 • 10^5 = 4.3 • 100,000 = 430,000
40,000 < 320,000 < 430,000
320,000 ÷ 40,000 = 8
X/49 = 21/x
x^2 = 21(49) = 1029
x = √1029 = 32.1
x = 32.1
Step-by-step explanation:
(x-9)²
= (x-9)(x-9)
= x²-9x-9x+81
= x²-18x+81
Answer:
The factors of given expression are 10+10√2 and 10-10√2.
Step-by-step explanation:
We have given a quadratic expression.
s²-20s-100
We have to find factors of given expression.
We use quadratic formula to find factors.
x = (-b±√b²-4ac) / 2a
From given expression, a = 1 , b = -20 and c = -100
Putting values in above formula, we have
x = (-(-20)±√(-20)²-4(1)(-100) ) / 2(1)
x = (20±√400+400 ) / 2
x = (20±√800) / 2
x = (20± √400×2) / 2
x = (20±20√2) / 2
x = 10±10√2
Hence, the factors of given expression are 10+10√2 and 10-10√2.
