A=2
B=9
81-4*2*c = 137
-8c=56
C=-7
2x² + 9x - 7 = 0
It is not a factor of x-5.Substitute 5 in the palce of x.Since the value is not equal to x,it is not a factor of x-5.
Answer:
yes
Step-by-step explanation:
The average weight of the three bags is ...
(55 +51 +48)/3 = 154/3 = 51 1/3 . . . pounds
By removing 3 2/3 pounds of sand from the heaviest bag, adding 1/3 pound to the middle-weight bag, and the remaining 3 1/3 pounds to the lightest bag, Ortega can make all of the bags weigh the same: 51 1/3 pounds.
54/9=6
the dog weighs 6*8 is 48 pounds
and the cat weighs 6 pounds
------------------------------------------------------
Define x :
------------------------------------------------------
Let the height be x.
Height = x
Length = 2x
------------------------------------------------------
Solve for x:
------------------------------------------------------
Area of triangle = 1/2 x base x height
64 = 1/2 (x)(2x)
x² = 64
x = √64
x = 8
------------------------------------------------------
Find the height and the length:
------------------------------------------------------
Height = x = 8 in
Length = 2x = 2(8) = 16 in
---------------------------------------------------------------------------
Answer: The base is 16 in and the height is 8 in.
