Answer:
4a²+3ab-a+a²
Step-by-step explanation:
So let's start off by simplifying this expression:
3a²-2ab+3b²-a+a²+5ab-3b²
Now let's subtract common terms XD
4a²+3ab-a+a²
7x+5y= 19
-7x-2y=-16 add because its a negative
-----------------
3y=3
y=1
then you find x by placing 1 for y
7x+5(1)=19
7x=14
x=2
(2,1)
Answer:
<u>2,160 mm³</u>
Step-by-step explanation:
<u>Q5</u>
- V = 1/2 × lwh
- V = 1/2 × 24 × 10 × 18
- V = 12 x 10 x 18
- V = 216 x 10
- <u>V = </u><u>2,160 mm³</u>
For example,
45/100 In decimal would be 0.45
45/1000 in decimal would be 0.045.
I didn't really explain, but I gave an example. Hope this helped you?
Answer: He was killed 24.83 hours before the body was found.
Step-by-step explanation:
Since we have given that

Here, T is the temperature of a body t hr after death, T = 82°F
T₀ is the air temperature , T₀ = 67°F
T₁ is the body temperature at the time of death = T₁ = 98.6°F
So, we will substitute all the values in the above equation.

Hence, he was killed 24.83 hours before the body was found.
