10x^2-6x^2 = 4x^2
-64-36 = 100
4x^2 -100 = 0
(2x -10)(2x+10)
X = 2/10 and x = - 2/10
Answer:
Step-by-step explanation:
False you must multiply the coefficient (numbers) and add the exponents.
A cause and effect relationship exist between two variables, when one
variable event is made to happen by the other variable.
The situation which best shows causation is option <u>B) The amount of time a </u>
<u>cell phone is used affects the charge of the battery</u>.

therefore, the more the cell phone is used, the battery power is used up
and therefore, the charge on the battery is reduced.
