Answer:
x = -3 + 
, -3 -
Step-by-step explanation:
Step 1: Isolate <em>x</em>'s
2x² + 12x = 7
Step 2: Factor
2(x² + 6x) = 7
x² + 6x = 7/2
Step 3: Complete the Square
x² + 6x + 9 = 7/2 + 9
(x + 3)² = 25/2
Step 4: Solve for <em>x</em>
√(x + 3)² = √25/2
x + 3 = 5√2/2
x = -3 ± 5√2/2
Answer:
Steps below
Step-by-step explanation:
(3/x²)+ 2/x =1 (x ≠ 0)
(3/x²) + 2x/x² = 1
(3 + 2x) / x² = 1
3 + 2x = x²
x² - 2x - 3 = 0
(x + 1) (x - 3) =0
x = -1 or x = 3
Answer:
its B replace the pitcher he has a higher ratio of wins
Step-by-step explanation:
Answer:
It would be A
Step-by-step explanation:
The other answers do not make sense.
First of all: Area= length x width.
Two of the options were larger than 49.7, so we could cross those out
Then, we look at A and B.
46.2 x 3.5 = 161.7, which is WAY larger than 49.7.
Since we have no option left to test, we can test A:
14.2 x 3.5= 49.7
Now we cam be sure that the answer is 14.2, or, A.
