I think his -4 because the E represents 2.5
Answer:
2
Step-by-step explanation:
Answer:
4!
Step-by-step explanation:
using the slope formula and the points (-1, 0) and (-2, -4) on the line:
-4 - 0 / -2 - -1 = -4 - 0 / -2 + 1 = -4 / -1, and since both the top and bottom are negative, they make a positive, giving you a positive 4
the slope formula is rise/run, or y2 - y1 / x2 - x1!
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.
