Answer:
LOOK IT UPP
Step-by-step explanation:
Most of these problems are the commutative property:
Addition
a + b = b + a
Multiplication
a * b = b * a
and the associative property:
Addition
(a + b) + c = a + (b + c)
Multiplication
(a * b) * c = a * (b * c)
There's also the Identity property:
Addition \ Subtraction:
a + 0 = a \ a - 0 = a
Multiplication \ Division:
a * 1 = a \ a / 1 = a
Answer: B. and E.
Step-by-step explanation:
B. is correct because m∠2 = m∠6 are alternate interior angles and alternate interior angles formed by parallel lines and a transversal are congruent.
E. x= 120°
m∠2 = m∠6=75°
∠6+x-15=180°
75°+x-15°=180°
60°+x=180°
x=180°-60°
x=120°
Answer:
A
Step-by-step explanation:
Real number is a value of a continuous quantity that can represent a distance along a line. The adjective real in this context was introduced in the 17th century by René Descartes, who distinguished between real and imaginary roots of polynomials. Example: 1.23939....
when you type in the answer A in calculator, you will get 3.464101615 as your final answer which is explain that answer A is a real number.
