Area of the pentagon: 342 cm2
Step-by-step explanation:
The figure of the pentagon is missing: find it in attachment.
The area of the pentagon can be seen as the area of 5 equal triangles, each of them having a base equal to the length of the side of the pentagon,
L = 14.1 cm
and the height of each triangle can be found by using Pythagorean's theorem:
The area of each of the 5 triangles is
Therefore, the area of the pentagon is 5 times this area:

Answer:
<h2>
<em><u>THE CORRECT OPTION IS D</u></em></h2>
<em><u>Given</u> </em>
<em> 4x+1 is a factor of p(x) = 4x³ + 5x² - 23x - 6,</em>
<em>so</em>
<em> 4x+1 =0</em>
<em>4x = -1</em>
<em>x = -1/4</em>
<em><u>Answer</u> -p(x) = 0 when x = -1/4</em>
It is b because the line intersects at (0,4) and the slope decreases by 2
The bus ride takes 25, and the bike ride takes 15, so 25+15=40. the 05 from 3:05 plus the 40 minutes it took him to get to soccer practice, locas arrives at 3:45
Answer:
A good prediction is that the number 5 will be rolled 8 times
Step-by-step explanation:
Here, we want to get the number of times 5 would occur in a roll of 50
firstly, we need the probability of having a 5 come up
To do this, we have to divide the number of 5’s by the count of possible numbers
We have this simply as 1/6
Now, we have to multiply this by 50
we have this as;
1/6 * 50 = 8.333
This is approximately 8
so we have it that in 50 rolls, we can have the number 5 coming up 8 times
