To find the original length you must take away the add-ons. To do so we know that they added 7 and A= l*l (or l squared). They added the 7 to the length so multiply 7*7 (49) subtract your answer from 169 (120) and that's your new area. To find the original length divide by 4 (I believe) and get 30m2
Answer: y=-3/1x+13
Step-by-step explanation: I just graphed the two points then found there slope and then I finished the line with the slope and then when I knew what was the y-intercept I finished the problem
You move the decimal 3.4, 2 places to the right and get 340 then you move the decimal 4.37, 2 placeto the right and you multiply 340 and 437 and you get 14858 and you move 3 decimal place to the left because you moved 3 decimal place so you have to move it back and you get 14.858
Answer:
13, 587 times
Step-by-step explanation:
Population of City A
= 1.9 * 105 = 157.5
Population of City B
= 1,070,000
Population of City C
= 2 * city B
= 2 * 1,070,000
= 2,140,000
The population of City C is how many times the population of City A?
City C = x * City A
2,140,000 = x * 157.5
x = 2,140,000 / 157.5
x = 13587.30
The population of City C is 13587.30 times the population of City A.
Hope this helps :)
X^2 - 14 = -10
x^2 = -10 + 14
x^2 = 4....take the square root of both sides, eliminating the ^2
x = (+-) sqrt 4
x = 2 and x = -2
