please can i have a brainliest
Perimeter is the sum of all the sides .The given sides are : 10a-4 ,6a+8,6a+8,12a
The given perimeter is 102 .We can form an equation:
10a-4+6a+8+6a+8+12a=102
Adding like terms :
34a +12=102
Subtracting 12 both sides:
34a= 90
Dividing by 34 both sides:
a=-2.65.
The given sides are :
6a+8= 23.9
12a= 31.8
10a-4=22.5
Among these 31.8 is the largest side .
So the side having 12 a length is largest.
Answer:
.571
Step-by-step explanation:
We need to find the total number of boys
11+5+4 = 20
And the total number of students
11+7+5+4+4+4 = 35
The Probability that the student is a boy is boy/total
P (boy) = boy/total
= 20/35
=4/7
=.571428571
to 3 decimal places
=.571
(cos Ф -cos Ф)² + (cos Ф + cos Ф)²
Firstly: (cos Ф -cos Ф)² = 0² = 0
Secondly :(cos Ф + cos Ф)² = (2cos Ф)². = 4. (cos Ф)² = 4cos² Ф
Mind you when you raise a cosine (or sin or tan...) to the n power, the n power should affect the cosine only and NOT the angle Ф
