Answer:
x = 12√2
Step-by-step explanation:
if its a square, all sides similar of 12 units.
then the bottom and side length is 12 units
we need to find x, the diagonal.
formula: a²+b² =c²
: 12² + 12² = c²
: c = √144+144
: c = √288
: c = 12√2
Therefore diagonal, x is 12√2
Answer:
It doesnt show anything
Step-by-step explanation:
45+5.25n>108
-45 -45
————————
5.25n > 63
Divide both sides by 5.25
n>12

Answer: B. Yes, d = 3</h3>
==============================================================
Explanation:
d = common difference, which is what we add on each time to get the next term
In this case, d = 3 means we add 3 each time to generate each new term
- -11+3 = -8
- -8+3 = -5
- -5+3 = -2
- -2+3 = 1
This pattern continues on forever.
--------------
Another way to see that d = 3 is to notice this is the difference between any two adjacent terms.
- d = term2 - term1 = -8 - (-11) = -8 + 11 = 3
- d = term3 - term2 = -5 - (-8) = -5 + 8 = 3
- d = term4 - term3 = -2 - (-5) = -2+5 = 3
- d = term5 - term4 = 1 - (-2) = 1 + 2 = 3
Each gap is 3 units wide, which helps us see we have an arithmetic sequence.
A sequence like {-11,-8,-5,-2,2} is not arithmetic because the gap between the terms of -11,-8,-5,-2 is 3, but the gap from -2 to 2 is not 3. So the gap must stay the same the entire time to get an arithmetic sequence.
