Answer:
B. 3(4+5) = 3(4) + 3(5)
Step-by-step explanation:
with distributive property, you multiply the number outside the parentheses to all of the numbers inside.
Answer: m= dependent variable , s =independent variable because the distance he runs depends on the time.
Step-by-step explanation:
In an experiment, the experimenter manipulates the<em> independent variable</em> to see the change in the <em>dependent variable.</em>
Here, Distance is the dependent variable that depends on time i.e. time = independent variable.
The meters he runs, m, in s seconds is given by the equation m=3s.
Thus, m= dependent variable , s =independent variable because the distance( meters) he runs depends on the time( seconds).
Answer:
Refer below for detailed explanation.
Step-by-step explanation:
Standard equation:
1. ax^2+bx+c=0.
Quadratic formula:
2. x = -b+-sqrt(b^2-4ac)/2a. .
Now two equations to find the factored form through these formulas above.
Through this identifying a,b and c.
ax^2+bx+c=0.
x^2+4x-21=0
Here a=1, b=4, and c= -21
Now applying in the quadratic formula.
x=-4+-sqrt(4^2-4(1)(-21))/2(1)
Now solve it and it becomes
x=3 or x= -7.
Another example :
x^2+3x-4=0
Here a=1, b=3 and c=-4.
X=-3+-sqrt(3^2-4(1)(-4))/2(1)
Now solve it and
x= -4 and x=1
P.s have attached the picture of quadratic formula as well.
