Answer:
length = 7 meters
Step-by-step explanation:
l = length
w = width
w = 3×l - 6
l×w = 105 m²
l×(3×l - 6) = 105
3×l² - 6×l = 105
l² - 2×l = 35
l² - 2×l - 35 = 0
solution of a squared equation is
(-b ± sqrt(b² - 4ac))/(2a)
a = 1
b = -2
c = -35
(2 ± sqrt(4 - 4×-35))/2 = (2 ± sqrt(4+140))/2 =
(2 ± sqrt(144))/2 = (2 ± 12)/2 = 1 ± 6
l1 = 1+6 = 7 meters
l2 = 1-6 = -5 meters, which did not make any sense for an actual object.
so, l = 7 meters remains.
Answer:
y is equal to 7
Step-by-step explanation:
the ratios on each side are 2 to 14, 9 to 63, and if you divide 14 by 2 you get 7. and if you divide 63 by 9 you get 7
Answer:
There is 2 apples
Step-by-step explanation:
Answer:
- 9 easy
Step-by-step explanation:
go ahead easiest thing ever lol
Divide 15 by 3 then multiply that number by 5.
15/3=5
5 x 5 = 25 apple pies.
think of it like this:
How many small groups of [3 blueberry pies] was in the group of 15. the answer is 5. so if the baker makes 5 for every three, and there are 5 threes, then there will be 25 apple pies. because 5 times 5 is 25.
