No it isn't because it wasn't an expression. An algebraic expression is a mathematical phrase that can contain ordinary numbers, variables (like x or y) and operators (like add,subtract,multiply, and divide)
Answer:
7×10^(-2)×8×10^5 = 56000
convert to scientific notation = 5.6 × 10^4
(scientific notation)
= 5.6e4
(scientific e notation)
= 56 × 10^3
(engineering notation)
(thousand; prefix kilo- (k))
= 56000
(real number)
Step-by-step explanation:
Answer:
B. The contradiction of the statement is proven false, so the original

Step-by-step explanation:
We assume the opposite and then get to a point where we get a false statement. That proves that the the opposite of the opposite ( what we originally wanted to prove) is true.
They both have 4 congruent sides and angles.
