2x^2+20x=-38 divide both sides by 2
x^2+10x=-19, halve the linear coefficient, square it, than add that value to both sides of the equation, in this case add (10/2)^2=25...
x^2+10x+25=6 now the left side is a perfect square
(x+5)^2=6 take the square root of both sides
x+5=±√6 subtract 5 from both sides
x=-5±√6 (so answer c.)
5(x+6) is the answer you are looking for. x represents a number
Answer:
(x2-x1)+(y2-y1)
Step-by-step explanation:
X2=0
X1=1
y2=9
y1=6
(0-1)+(9-6)
-1+3
2
Answer:
The smallest possible value for x is 
Step-by-step explanation:
we know that
The <u>Triangle Inequality Theorem</u>. states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side
so
The value of x must be greater than 
so
If x must be a whole number
therefore
The smallest possible value for x is
Answer:
The second one (B)
Step-by-step explanation:
u don't multiply a number by the same number if u know what I mean
hope this helps <3
