Answer:
Step-by-step explanation:
(9 + m)(-m + 9) = (9 + m)(9 - m) {(a+b)(a-b) = a² - b²}
= 9² - m²
= 81 - m²
= -m² + 81
5/3 as a fraction or 1 2/3 segments per person.
It’s either a or c because it’s not a straight line so it’s definitely not b or d
This is the concept of algebra, to solve the question we proceed as follows;
the current number of women is:
1/4*20=5 women
the percentage of women is:
1/4*100=25%
therefore for the team to have 40% women, the number of women should be:
40/25*5
=8 women
The answer is 8 women
Answer:
Step-by-step explanation:
<u>It shows combination of:</u>
- m∡EBD = 180° and
- m∡EBC + m∡CBA + m∡DBA = m∡EBD
<u>m∡EBD in the first equation is substituted with 180° in the second and it results in:</u>
- m∡EBC + m∡CBA + m∡DBA = 180°
<u>Correct choice is:</u>
