Answer:
yes
Step-by-step explanation:
Answer:
A. 13m
Step-by-step explanation:
To find the area of a square you multiply Length by the Height. Since squares have equal length sides the number has to be the same for the length and the height.
13 x 13 = 169

Your answer would be -2x-6
The correct answer is:
[C]: "
a = ±
" .

___________________________________________________________Explanation: _________________________________________________________We are given:
_________________________________________________________ </span>
→ "
25 = a² + b² " ; Solve for "
a" ;
_________________________________________________________ → To solve for "
a" ; we want to isolate "
a" on one side of the equation.
_________________________________________________________We can rewrite: "
25 = a² + b² " ;
as: " a² + b² = 25 " .
_________________________________________________________
Then, we can subtract "
b² " from each side of the equation; as follows:
_________________________________________________________
→ " a² + b² − b² = 25 − b² " ;
to get:
_________________________________________________________ → " a² = 25 − b² " ;
_________________________________________________________ → Now, take the square root of EACH SIDE of the equation ;
to isolate "
a" on one side of the equation; & to solve for the value(s) of "
a" ;
_________________________________________________________ → √(a²) =

;
to get:
_____________________________________________________ → a = |
| ;
→ a = ±
;
→ which is:
Answer choice: [C]: "
a = ±
" .

Answer: Maturation
Step-by-step explanation:Internal validity is a type of validity that establishes a cause and effect relationship,this type of validity tries to eliminate alternative explanation for a Discovery.
One of the threats to internal validity is MATURATION.
MATURATION is the type of threat occuring during experiment to prove a particular Discovery as shown by the question where the police officer shot and killed someone against the intention of the experiment.
