Answer:
2 x 7
Step-by-step explanation:
a * b = 14
2a + 2b = 18
(a * b)/b = 14/b Dividing both sides by b
a = 14/b
Substitute a in the perimeter equation
2(14/b) + 2b = 18
28/b + 2b = 18
2b - 18 + 28/b = 0
Multiply both sides by b
2b^2 - 18b + 28 = 0
Divide both sides by two
b^2 - 9b + 14 = 0
The Factors of 14 include -2 and -7 which add up to -9
(b - 2) * (b - 7) = 0
This has two answers because b can be either the side that is 2 long or 7 long, so there's no need to go back and solve for a.
2 x 7
B = √(14² - 9²) = √(196-81) = √115 ≈ 10.7 units
The answer is 19 packages of popsicles. You would multiply 19 and 3 and get 57. After you get 57 you subtract 3 and end up with 54
The distance he has traveled vertically to the nearest yard in combined trip is 111 yards.
<em><u>Solution:</u></em>
Given that,
Each step is 8 inches high
There are a total of 50 stairs
So the height of 50 stairs is:
Height of 50 stairs = 50 x 8 = 400 inches
Joseph makes 10 round trips up and down the stairs
So, joseph has went up 10 times and he came down 10 times
We need to find the distance he has traveled vertically in the combined trips
Therefore,
Number of times he went up = 10
We know that,
height of 50 stairs = 400 inches
Therefore,
Distance traveled up = 10 x 400 = 4000 inches
Convert to yard
1 yard = 36 inch
Therefore,

Therefore, the distance he has traveled vertically to the nearest yard in combined trip is 111 yards
Answer:
a) -20/11 b) -10/7
Step-by-step explanation:
a) m=(y2-y1)/(x2-x1)
m=(-4-16)/(4-(-7))
m=-20/(4+7)
m=-20/11
b) m=(y2-y1)/(x2-x1)
m=(-10-(-20))/(-12-(-5))
m=(-10+20)/(-12+5)
m=10/-7
m=-10/7
