Answer:
9.899495
Step-by-step explanation:
=(0−(−7))2+(−6−1)2−−−−−−−−−−−−−−−−−−−√
d=(7)2+(−7)2−−−−−−−−−−√
d=49+49−−−−−−√
d=9–√8
d=9.899495
25d^2-30d-35d+42=25d^2-65d+42.
To reverse a percentage decrease you divide it by the decrease (+ 100%)
For example we will pick the number, 100, which is decreased by 15% to 85.
To make 85 back to 100 we divide it by the decrease (1-0.15):
85 / 0.85 = 100
To find out how much 85 increased to get back to 100, we do:
15 / 85 = 0.1765 = %17.65
15 is the reduction/difference, and 85 is the with reduction total.
Because percentages stay the same, this is applicable to any numbers, from this, we know that whenever something is reduced by 15% - when restored to it's original is increased by %17.65
The answer is %17.65
Independent because the ratio of the second cube is the same (1:6), and it isn't affected by the result of the first cube
