Answer:
(B , D) = (-2,5)
Step-by-step explanation:
The given quadratic expression is
compare the given expression with 
so we have 
now 
and 
we need to find two numbers such that their product is -30 and sum is -1
-6 and 5 are such numbers
so we have
grouping first two terms and last two terms
factor out 3x from first two terms and 5 from last two terms
( factor out (x-2))
hence B =-2 and D= 5
(B,D)= (-2,5)
There is only one quadrilateral with no right angles -"kite"

Answer:
1 5/8 days
Step-by-step explanation:
Days spent on English : 5 3/8 = 27/8 days
Days spent on science: 3 1/4 = 13/4 days
Days spent on math 1 1/2 = 3/2 days
Days spent on English and math = 27/8 + 3/2 = 27/8 + 12/8 = 39/8 days
Difference between English+math and science: 39/8 - 13/4
= 39/8 - 26/8 = 13/8 or 1 5/8 days
Tim's wrapping paper
15 - (4 1/3 + 5 3/8)
= 15 - (13/3 + 43/8)
= 360/24 - (104/24 + 129/24)
= (360 - 233)/24
= 127/24
= 5 7/24 feet
