Answer:
Step-by-step explanation:
Split these into two separate squares.
One has side lengths of x + 3, and the other has side lengths of x + 1.
<u>We'll solve the first square first.</u>
Here is the expression we want to use:
*
Use FOIL (first, outer, inner, last).
Simplify.
<u>Time for the second square!</u>
This goes similarly to the first one, so I'll omit any words and you can follow along with the math.
*
<u>Now, we'll add them together.</u>
Combine like terms.
And we're done!
Answer:
ok
Step-by-step explanation:
yes
Answer:
Parallel.
Step-by-step explanation:
We need to convert the 2 equations to slope-intercept form (in bold) :-
2x + y = 8
y = -2x + 8.
6x + 3y = 12
3y = -6x + 12
Divide through by 3:
y = -2x + 4.
The slopes are the same (both -2), so they are parallel.
For this case, from the diagram we can conclude the following results according to the surveys:
For Dogs:
Dogs = 24 + 31 = 55
No dogs = 10
Total = 65
For the cats:
Cats = 10 + 31 = 41
No cats = 24
Total = 65
