Answer:
An expression will be said to be a perfect square trinomial if it takes the form of ax² + bx + c and if it satisfies the condition b² = 4ac.
Step-by-step explanation:
An expression which is obtained from the square of a binomial equation is known as perfect square trinomial.
Now, the conditions for which an equation will be called a perfect square trinomial are;
i) It is of the form: ax² + bx + c
I) It satisfies the condition: b² = 4ac.
Thus, the perfect square formula could take the following forms:
(ax)² + 2abx + b² = (ax + b)²
Or
(ax)² − 2abx + b² = (ax − b)²
Answer:
The jet could fly 3,525 miles in 15 hours.
The rate of speed is 235 miles an hour.
Step-by-step explanation:
Step 1- Find the rate of speed
470÷2= 235
235 miles an hour
Step 2- Multiply
235×15= 3,525
The union of two sets<span> A and B is the </span>set<span> of elements which are in A, in B, or in both A and B. In symbols, . For example, if A = {1, 3, 5, 7} and B = {1, </span>2<span>, 4, 6} then A ∪ B = {1, </span>2<span>, 3, 4, 5, 6, 7}.
The intersection of 2 sets depict elements that appear in both sets (all elements in B that also appear in A). In the Venn diagram, the intersection of the sets are always in the middle of both sets. I attached a photo to show you the perfect example of the intersection of sets.
I hope it helps :)</span>
