From what my calculator said, Radical 7 is 2.6457511311064591 (why not m8) and obviously 2.65 is not bigger than 3.5 or 3.444
Answer:
Options (A), (B)
Step-by-step explanation:
Option A.
Two sides of the given triangle are equal. Therefore, the given triangle is an isosceles triangle.
Option (B).
Given triangle has a right angle. Therefore, it's a right triangle.
Option (C).
Only two sides of the given triangle are equal. Therefore, it's not an equilateral triangle.
Option (D).
Although this triangle has two acute angles (less than 90°) but the third angle is 90°. Therefore, this triangle is not an acute triangle. It's a right triangle.
Option (E).
A scalene triangle is a triangle having all sides different in measure but the given triangle is an isosceles triangle. Therefore, it's not a scalene.
Option (F).
Any angle of this triangle is not more than 90°. Therefore, the given triangle is not an obtuse triangle.
Answer: B. 100-h < 40+2h
Step-by-step explanation: If it says the first tank is less it probably is B and not D.
Answer:
x > -9
See the second scenario if incorrect.
Step-by-step explanation:
1...x^(2) + 9x < 0
first factor
2...x * ( x + 9 ) < 0
now divide by x
note: 0 divided by any number is 0
2... x * ( x + 9 ) < 0
/x /x
3... x + 9 < 0
now subtract 9
3... x + 9 < 0
-9 -9
4... x< -9
Second scenario
In the event that x is a negative number
2... x * ( x + 9 ) < 0
dividing by x will flip the inequality sign
(3)... x + 9 > 0
subtract 9
(3)... x + 9 > 0
-9 -9
(4)... x> -9
Answer:
( x + 2 ) and ( x - 11 )
Step-by-step explanation:
x² - 9x - 22 = 0
x² + 2x - 11x - 22 = 0
x ( x + 2 ) - 11 ( x + 2 ) = 0
( x + 2 ) ( x - 11 ) = 0
Factors of x² - 9x - 22 are ( x + 2 ) and ( x - 11 ).
