Answer:
6 * 10 * 6
Step-by-step explanation:
Answer:
x > 0 where x = any real number
Step-by-step explanation:
If we divide any number by 0 then the answer is Undefined
In option 1
x is greater than 0
In option 2
x is Less Than or equal to 0
In option 3
x is greater than or equal to 0
In option 4
x is Less Than 0
As the above statement any number which is divided by 0 the answer is always Undefined
Thus, Option 1 is correct
x > 0 where x = any real number

7 times 2=14
14 times 2=24
24 times 1=24
1.) 5 (3a + 4c = 67)
2.) -3 (5a + 6c = 106)
1.) 15a + 20c = 335
2.) -15a - 18c = -318
_____________________
2c = 17
divide both sides by 2
c = £8.5
substitute c for 8.5 to find a
3a + 4 * 8.5 = 67
3a + 34 = 67
subtract 34 from both sides
3a = 33
divide both sides by 3
a = £11
Hope this is helpful
Answer:
Step-by-step explanation:
Note that the quadratic formula has that "plus or minus" due to our taking the square root of some quantity. No square root is involved in the two formulas you've posed.
I have two suggestions here:
1) Write " (x plus or minus y)^2 = x^ plus or minus 2 times xy + y^2 " Note that a + on the left side corresponds to a + on the right side, and same with - .
2) Memorize these two formulas, which in most algebra textbooks you'll find in the section "special products and factoring."
