Answer: D
Step-by-step explanation:
A quadratic function has a degree of 2 so there will be two roots. The statement says the function does NOT CROSS THE X-AXIS so there are no real roots. That means both roots must be imaginary (complex).
- The commutative property is a number property where the answer obtained is the same no matter the position of the numbers you are multiplying together.
- Commutative property of multiplication is expressed as:
a x b = b x a
a x b x c = a x c x b = b x c x a
- Note: " . " in the question also means "x" (multiplication)
- Applying commutative property to the question:
(7/15)⋅(−11)⋅(30)
(7/15) ⋅ (−11) ⋅ (30) = (7/15) . (30) . (11)
The values interchanged are: 11 and 30. The result of the multiplication remains unchanged.
Option A is the correct answer.

Answer: 2.0
Step-by-step explanation:
The given expression : 
To solve the given expression , we need to follow BODMAS (Bracket→ Of Divide→ Multiplication →Add →Subtract).
According to BODMAS , first we simplified the expression present inside the brackets .
[10= LCM[10,5]]
[Multiply]
[Simplify]
[Add]
Hence, the value of the expression in the simplified form = 2.0
Answer:
Angle x= 60°
Step-by-step explanation:
For the triangle HIL, you're going to add 30+90=120
Angles in a triangle add up to 180.
So, therefore,
180-120=60 so angle L must equal 60.
HJ is a straight line and angles in a straight line add up to 180.
180-90=90
Angle JIL is equal to 90.
To find y you add 90+45 which equals 135.
Again, angles in a triangle add up to 180.
180-135=45
So,
y = 45
Now we are told that IJK is a right angle and that we are given that IJL is 45. 45 is half of 90 so LJK must be 45.
To find angle JLK we must add angle L and angle y.
60+45=105
Angles in a straight line add up to 180. So,
180-105=75
75 = Angle JLK
75+45=120
Angles in a triangle add up to 180 so,
180-120= 60
Angle x= 60°
