He has 11 hours of daylight each day. Each solar panel has an area of 3 m2. 800 Watts of sunlight hit each 1 m2 of solar panel every hour. However, the solar panels are only 14.5% efficient, which means they can only absorb 14.5% of the 800 watts. He needs 20,000 Watts of stored energy to fully charge the rover battery. How many solar panels will he need to bring on the trip to be able to fully charge an empty rover battery ?

Step-by-step explanation:

i can answer this question sweetie!

step-by-step explanation:

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
