Expand the binomial:
(√2/5 + 5/2 <em>i</em> )² = (√2/5)² + 2<em>i</em> (√2/5) (5/2) + (5/2 <em>i</em> )²
… = 2/25 + √2 <em>i</em> + 25/4 <em>i</em> ²
… = -617/100 + √2 <em>i</em>
4/7 × 3/4
(4 and 4 are cancelled )
7×3
the answer is 21
Answer:
x=24.8
Step-by-step explanation:
Answer:The Alternate Exterior Angles Theorem states that if a pair of parallel lines are cut by a transversal, then the alternate exterior angles are congruent. Here we have a new pair of lines, parallel and crossed by a transversal.
