8^1 = 8
these answers are equivalent
(2xy)^3= 2^3 * x^3* y^3= 8 x^3 y^3
2xy^3= (2xy)* (2xy)*(2xy)
equivalent as well
Answer:
After how many days will the tank need to be refilled?
Step-by-step explanation:
To answer our question, we first need to figure out what d represents. d is multiplied by 0.035, which is how much the water level decreases daily. Since it decreases daily, the overall amount it decreases depends on how many days have passed. It is logical then to deduce that d represents days (also days starts with d, so we know we're on the right track haha).
The equation equals to 4, the water level at which the tank must be refilled, so we know we are looking for d when the tank must be refilled.
Answer:
The equivalent expression is
Step-by-step explanation:
The distributive property says for any numbers <em>a, b c</em>, and <em>d</em>
which basically says you should multiply the coefficient by every term in the parenthesis to get an equivalent expression.
Applying the distributive proper to the expression we get:
which is an equivalent expression to .
