Looks like a whole lot of fun you got there... Okay.. so first you'd have to add up the two values on the left side by multiplying the top and bottom of the first by the denominator of the second and by multiplying the top and bottom of the second by the denominator of the first, like this (sorry for all the parentheses) :
[x(x-4)]/[(x+4)(x-4)] + [4(x+4)]/[(x+4)(x-4)]. now you can add them together:
[x(x-4)+4(x+4)]/[(x+4)(x-4)] then i'd try to combine the top:
x^2-4x+4x+16 or x^2+16, then i'd combine the bottom (since i just noticed something awesome here):
x^2-4x+4x-16 or x^2-16. This makes the left side look exactly like the right ( isn't that awesome!) This means x = 1!
Answer:
The slope of the line= 2/3
Step-by-step explanation:
(2, 2)=(x, y) and (5, 4)=(`x, `y)
The formula for finding slope= `y-y/`x-x
4-2/5-2
2/3
Therefore, the slope=2/3
Answer:
195
Step-by-step explanation:
Of means multiply and is means equals
40% * number = 78
Change to decimal form
.40 * number = 78
divide each side by .40
.40 number/ .40 = 78/ .40
number =195
Answer: GCF = 1
Step-by-step explanation:
A factor is a whole number that when multiplied by another whole number equal given number.
Factors of 19: 1 and 19
Factors of 13: 1 and 13
The only factor the two numbers have in common is 1
