If xy=0 assume that x and y=0
so
(2x-8)(7x+5)=0
assume
2x-8=0 and 7x+5=0
solve each
2x-8=0
2x=8
x=4
7x+5=0
7x=-5
x=-5/7
so x=-5/7 or 4
Answer:Se dice que cualquier número que no se pueda expresar como una razón de dos enteros es irracional. Su representación decimal no termina ni se repite infinitamente, sino que se extiende para siempre sin repetición regular. Ejemplos de números tan irracionales son la raíz cuadrada de 2 y π.
Step-by-step explanation:
Answer:The distributive property of equality
Step-by-step explanation:the 8 was distributed into the -6
Answer:
^62 with a numertor of 66 you divide by .21
Step-by-step explanation:
The first thing you should know are properties of exponents to solve the problem.
For this case the radical form is given by the writing of the expression in the form of root.
We have then:
t^-3/4 =4^root(t^-3)=4^root ((1)/(t^3))
answer t^-3/4=4^root((1)/(t^3))
