2x²-2x-12=0
simplify it into x²-x-6=0
factored form: (x-3)(x+2)=0
solutions: x-3=0 or x+2=0
x=3 or x=-2
Not sure how to explain "what the solutions mean for the equation". One thing you can say is that the solutions mean the equations have two roots/two zeros: 3 and -2, or the graph of 2x²-2x-12 intersects the x axis at (3,0) and (-2,0).
Answer:
<u>The correct answer is A. Divide both sides by positive 5</u>
Step-by-step explanation:
Let's solve the equation for finding z and the necessary steps to do it:
5z - 3 = 12
5z = 12 + 3 (Adding 3 at the right side and subtracting 3 at the left side)
5z = 15 (Adding 12 plus 3 at the right side)
5z/5 = 15/5 (Dividing by positive 5 at both sides)
<u>z = 3</u>
<u>The correct answer is A. Divide both sides by positive 5</u>
Ur answer is B
hope i helped best of luck :)
Answer:
49
Step-by-step explanation:
-11 2/3 x (-4 1/5) =
negative times negative = positive
Change the mixed numerals into fractions.
= 35/3 × 21/5
Multiply the numerators together. Multiply the denominators together.
= (35 × 21)/(3 × 5)
Simplify.
= (7 × 5 × 7 × 3)/(3 × 5)
Divide the numerator and denominator by 3 and by 5.
= 7 × 7
= 49
