12 inches = 1 foot, so 6 feet = 72 inches
10:72, reduces to 5:36
The answer for the expression is C.
Answer:
Step-by-step explanation:
we will use distributive property to write an equivalent expression:
7(-2x)+7(6)
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)
Answer:
It is a proportional relationship
Step-by-step explanation:
To see if multiple ratios are proportional, you could write them as fractions, reduce them, and compare them. If the reduced fractions are all the same, then you have proportional ratios.The equation that represents a proportional relationship, or a line, is y=kx, where k is the constant of proportionality.
Hope this helps
the constant of proportionality is 2
