Answer:
The missing coefficient of the x-term of the product (-x-5)2 is 10.
Step-by-step explanation:
<h3>
Solution:</h3>
Through whole square formula.
(-x-5)2 = (-x)^2 -2(-x)(5)+(5)^2
=x^2+10x+25
Therefore, the missing coefficient of the x-term of the product is 10
Answer:
A
Step-by-step explanation:
2x² + 5x = 12
2x² + 5x - 12 = 0
x² + 5x - 24 = 0
factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24. the only pair that adds to 5 is 8 and 3
2x² - 3x + 8x - 12 = 0
split the equation and factor
2x² - 3x = 0 ||| 8x - 12 = 0
x(2x - 3) ||| 4(2x - 3)
therefore the pair is (2x - 3)(x + 4)
2x - 3 = 0
2x = 3
x = 3/2
or
x + 4 = 0
x = -4
1/6 = 10 minutes
10 minutes six times =1hour
1/8 x 6 =3/4
Answer:
Step-by-step explanation:
break it into pieces
put it all together
*since there's no negative in front of the other numbers except 7 they're positive so you add them*
simplify
Answer:
The correct option is (a+b)+c
Step-by-step explanation:
The correct option is (a+b)+c
According to the Associative property for Addition:
a+(b+c)=(a+b)+c
The associative property states that you can add or multiply regardless of how the numbers are grouped.
.If you are adding or multiplying it does not matter where you put parenthesis.
Thus the correct option is A....
