Answer:
Step-by-step explanation:
observe
||a–b+c|| = ||a+b+c||
(a-b+c)² = (a+b+c)²
(a+b+c)² – (a-b+c)² = 0
((a+b+c)+(a-b+c))((a+b+c)–(a-b+c)) = 0
(2a+2c)(2b) = 0
(a+c)b = 0
a•b + c•b = 0
||a||×||b||×cos(π/8) + ||c||×||b||×cos(θ) = 0
Since the percent increase is bigger than 100%, it definitely has to be more than 54,000.
so let's break this down:
250%= 100% + 100% + 50%
we know 100% is the whole price so if there are 2 100% we have to multiply the price by two!!!
54,000•2 = 108,000
now, 50% is half of the whole price, divide the price by two:
54,000÷2= 27,000
so add your results and you will get this!
108,000+27,000= 135,000
Answer: t+20 = 60
Step-by-step explanation:
Answer:
12 meters
Step-by-step explanation:
2x9=18 (get both widths)
42-18=24 (take away widths of 9m)
24/2=12 (divide by 2 to get one length)
