Answer:
c.positive
Step-by-step explanation:
A. Median. That is simply what it is called
Answer:
which are selectable. it should equal 563.76
2x² = 7x + 6
Subtract both terms so that we can get 0 on one side.
2x² - 7x - 6 = 0
Find what factors of - 12 (2 * - 6) add up to be - 7. It's - 4 and - 3.
2x² - 4x - 3x - 6 = 0
2x(x - 2) - 3(x - 2) = 0
(x - 2)(2x - 3) = 0
Now set each equal to 0.
x - 2 = 0
x = 2
2x - 3 = 0
2x = 3
x = 3/2
x = 3/2, 2
Answer:
Part A: 2D + 3 = A
Note: I have likely given you the answer to the whole problem. See below.
Step-by-step explanation:
Givens
- Alan = A
- Bruce = B
- Cecil = C
- Dylan = D
Comment
You have to pay the most attention to Alan and Bruce. Once you have equations for those two. Cecil's weight is just the sum of those two.
<em>Alan</em>
Alan = Twice*Dylan + 3 or
A = 2*D + 3
<em>Bruce</em>
Bruce = three * Dylan - 12
B = 3*D - 12
<em>Cecil</em>
Cecil = Alan + Bruce
C = A + B
Note
The last equation shows you how to combine the first two.
C = A + B
A = 2D + 3
B = 3D - 12
C = 2D + 3 + 3D - 12
C = 5D - 9
