Answer: 4z + 28
Step-by-step explanation:
We can distribute the 4 to each term inside the parenthesis.
So 4(z+7) = 4*z + 4*7
= 4z + 28
Answer:
Step-by-step explanation:
Given
at 9 am temperature of the body is 
1 hr later temperature 
Temperature of room 
According to newtons law



Integrating



Now at 9 am i.e. t=0,


At 10 am i.e. t=1 hr T=89



Temperature of Normal human body is 


Taking log both sides

i.e. 5 hr and 16.2 min
i.e. victim murdered at 3 am and 43.8 min
Answer:
x=-32/29

Step-by-step explanation:
3x+4y=36 Equation 1
-5x+3y=35 Equation 2
Multiplying equation 1 with 3 (value before y in equation 2) and equation 2 with 4 (value before y in equation 1) we obtain equations 3 and 4 as follows
9x+12=108 equation 3
-20x+12y=140 equation 4
Subtracting equation 3 from equation 4 we obtain
-29x=32
x=-32/29
To find the value of y, we substitute the value of x into equation 2 as initially given in the equation
-5(-32/29)=35-3y
-5(-32/29)-35=-3y

Answer:
2 x 5
Step-by-step explanation:
in prime factorization, we divide until it gets to 1. In the case of 10 divide by 2 which will give you 5 divide by 5. Thats how I got 2 x 5
