1) In this problem, we can see that this is an isosceles right triangle.
2) So, one way of solving it is to make use of the Pythagorean theorem. Note that an isosceles triangle has two congruent sides, so we can write out:
Usually, we rationalize it. But since the question requests the denominator to be a rational one, so this is the answer.
$66. Since he worked 5.5 hours at a rate of $12 per hour, you can simply multipy the amount of hours worked by the rate. $12 x 5.5hr = $66.
Do you mean 7?
You need to multiply each like term differently ( 1. Coefficient, 2. M term, 3. N term, and 4. O term)
1. The coefficients are 4 and 7, and as you have already solved, that equals to 28.
2. The m terms are (m • m) because there is one m in (4mno) and one m in (mn). m • m would equal to m^2.
3. The n terms are (n • n^2 •n) because there is one n in (4mno), n^2 in (7n^2o^2), and one n in (mn). They would equal n^4.
4. The o term would stay as o^2 as there are not other o terms.
To piece it all together, your answer would be 28m^2n^4o^2, or 28 • m ^2 • n^4 • o^2.
The zero or the ° represents degrees.
I hope this helps :)
Answer: 1/12
Step-by-step explanation: If you multiply the two factors, you would technically get -1/12, but since there are 2 -'s -*-=+
