Answer:
B for the first one , and C for the second
Step-by-step explanation:
for the first question DEG which is 60, and GEF which is 120, would equal to 180 degrees, which would be DEF because its a linear pair.
For the second question the are alternate exterior angles, so the are opposite of each other and on the outside.
6+6=12 + 6= 18
6x3=18
(I feel like u know the answer, just asking to give away free points. Either way the answer is 18 and thank you.)
Answer:
By closure property of multiplication and addition of integers,
If
is an integer
∴
is an integer
From which we have;
is an integer
Step-by-step explanation:
The given expression for the positive integer is x + x⁻¹
The given expression can be written as follows;

By finding the given expression raised to the power 3, sing Wolfram Alpha online, we we have;

By simplification of the cube of the given integer expressions, we have;

Therefore, we have;

By rearranging, we get;

Given that
is an integer, from the closure property, the product of two integers is always an integer, we have;
is an integer and
is also an integer
Similarly the sum of two integers is always an integer, we have;
is an integer
is an integer
From which we have;
is an integer.
Answer:
Step-by-step explanation:
<u>Use the formula:</u>
- degrees/360° = L/circumference
- or
- radians/π = L/circumference
<u>As per given:</u>
l = 12 feet, r = 10 feet
- degrees = 360°*12/(2*3.14*10) = 68.78°
- radians = π rad *12/(2π*10) = 0.6 rad
Answer:
The value of given expression for x = - 10 is - 81
Step-by-step explanation:
Given expression as :
3
x - 2 
Or, 3 +
x - 2 -
Or,
x - 
or,
Now for x = - 10

Or, 
∴ - 76 - 5
Or, - 81
Hence The value of given expression for x = - 10 is - 81 Answer
