Hello! :) have a good day!
−2d + 5
Answer:
= a⁴
Step-by-step explanation:
(a)(a)(a)(a)
a se multiplica por si misma 4 cuatro veces así que:
(a)(a)(a)(a) = a⁴
Most fool-proof way to do this in my opinion is to simply expand everything and write it out, i.e.

Throwing this into a calculator, we get
23.032To the nearest cent, this gives us
$23.03
The equation of c is an illustration of subject of formula
The equation of c in terms of r and t is c = r - 15/t
<h3>How to determine the equation?</h3>
The equation is given as:
t = 15/(r - c)
Cross multiply
t(r - c) = 15
Divide both sides by t
r - c = 15/t
Subtract r from both sides
-c = -r + 15/t
Multiply both sides by -1
c = r - 15/t
Take LCM

Hence, the equation of c in terms of r and t is
