That picture is trying to tell us the area is
A = x² - 12x + 36
A = (x - 6)²
Since for a square
A = s²
s² = (x - 6)²
s = |x - 6|
Answer: |x-6|
A+B=15 —>A+15=B(plug this into the other equation)
60a+30b=600
60a+30(a+15)=600
60a+30a+150=600
90a+150=600
90a=450
A=5 (plug back in to first equation)
A+B=15
5+B=15
B=10
They have 5 of the Model A and 10 of model B.
Which method? There is the substitution method, elimination method, and comparison method
(y x .12) x .3 = the total cost
Answer:
$1129.93
Step-by-step explanation:
100 - 9.5 = 90.5
8000 - 90.5 = 7909.5
7909.5 ÷ 7 = 1129.93
i hope this helps
