Answer:
The rate is 
degree per hour.
Step-by-step explanation:
Given : A scientist conducted an experiment. Due to chemical reaction, the temperature of a compound rose 
degree every 
hour for a limited time.
To find : What was the rate, in degrees per hour that the temperature of the compound rose ?
Solution :
In every hour the temperature of a compound rose degree
To get the rate, in degrees per hour,
In every 1 hour the temperature of a compound rose is
degree
degree/hr
degree/hr
Therefore, the rate is degree per hour.
X= base
one side= x-6
other side= 4+x
x+x-6+4+x = 43
3x=43+2
x=15 length of base
Answer:
Solution is given by (-2,-1)
Step-by-step explanation:
2x-3y = -1
11x-9y = -13
Multiplying equation 1 by -3 and adding it to equation 2 ,we get
-6x+9y = 3
11x -9y = -13
___________
5x = -10
gives x = -2
plugging this value in equation (1) ,we get
2(-2) -3y = -1
-4 -3y =-1
-3y =-1+4
-3y =3
y = -1
solution is (-2,-1)
When I multiplied the terms here is the answer.
54 + 32 = 86
