Answer:
the word similar means when to things are alike, it compares to congruent because congruent means thing are in harmony.
Things I would say are similar is a blanket and a sheet because they both provide coverage and warmth.
If I said things are similar it is because they are alike in meanings, or appearence.
I would use similar over congruent because congruent isn't a word you hear often. When you do hear it is mostly used to talk about angles and lines.
Answer:
<h2>642 4/5</h2>
Step-by-step explanation:
5 into 3 (0 times)
Bring next number down 3214 ⬇️
5 into 32 (6 times, 2 left over)
Bring next number down 3214 ⬇️
5 into 21 (4 times, 1 left over)
Bring next number down 3214 ⬇️
5 into 14 (2 times, 4 left over)
Bring next number down 3214.0 ⬇️
5 into 40 (8 times)
642.8 = 642 4/5
3214 divided by 5 is 642 4/5.
I'm always happy to help :)
Answer:
Step-by-step explanation:
This is a quadratic equation. We'll find the discriminant, but must first rewrite this equation in standard form:
5w2 – 2w + 4 = -4 + 4, or 5w^2 - 2w + 4 = 0
The coefficients of the w terms are {5, -2, 4}
and so the discriminant b^2 - 4ac is 4 - 4(5)(20) = -396
Because the discriminant is negative, we know that there will be two unequal, complex solutions.
Answer: (x + 7)(x - 7)
Explanation: If a variable is taken to an even power, that variable is a perfect square. In this case, x² would therefore be a perfect square.
Since 49 is also a perfect square, what we have here is the difference of two squares. That can be factored as the product of two binomials one with a plus in the middle and one with a minus in the middle.
In the first position will be the factors of x² that are the same.
So we have <em>x</em> and <em>x</em>.
In the second position we will have the
factors of 49 that are the same, 7 and 7.
(x + 7)(x - 7) is your answer which is a factored version of x² - 49.
