Answer:
m=29
Step-by-step explanation:
add 20 to both sides and that is what m equals
Answer:
The answer is: 4,500,000 kilometers or in scientific notation: 4.5 x 10^6 kilometers.
Step-by-step explanation:
Multiply to get the answer:
300,000 * 15 =
4,500,000 km
In scientific notation: 4.5 x 10^6
Answer:
I think it is the 3 one
Step-by-step explanation:
Short Answer B
Argument
A
A will give you x = +/- 5i
x^2 + 25 = 0
x^2 = - 25 Take the square root.
sqrt(x^2) = +/- sqrt(-25)
x = +/- (5)i which is a complex number.
B
Is the answer
x^2 = 25
sqrt(x)^2 = sqrt(25)
x = +/- 5
C
Can't be factored just by looking at it. You can show that C is not true just by putting 5 into the equation
f(x) = x^2 + 10x - 25
f(5) = 25 + 10*5 - 25
f(5) = 50
C is not true.
D
D can be eliminated as C was
f(x) = x^2 - 5x - 25
f(5) = -25 ( l'll let you show this is not true). 5 is not a solution because it does not make f(x) = 0
Try subtracting first there were 10 then four were sold I don't know what happens after but thats what I know
