Answer:
<u>The correct answer is 58.82 square meters of solar panels will be needed to supply 2 kilowatts</u>
Step-by-step explanation:
Solar cell energy supply = 34 watts per square meter
Therefore, 100 square meters will supply 3400 watts which is 3.4 kilowatts.
How many square meters of solar panels would you need to 2 kilowatts?
Total energy = 2 kilowatts = 2,000 watts
Number of square meters = Total energy/Solar cell energy supply
Number of square meters = 2,000/34
<u>Number of square meters = 58.82</u>
<u>It will be necessary 38.82 square meters of solar panels to supply 2 kilowatts</u>
Answer:
t > 700
Step-by-step explanation:
1000 - 300 = 700
This means they still need at least 700 toys to go.
In the question it says "donate more" so we are going to use the ">" symbol.
Let "t" equal the number of toys they need to donate.
t > 700
Best of Luck!

Hope this helped :)
Let the no be X and Y
acc to ques....
x-y=9 .........1
xy=162 ..........2
substituting value from 1 in 2 we get;
x=9+y
[9+y][y] = 162
y^2+9y = 162
y^2 + 9y - 162=0
y^2 + 18y - 9y - 162=0
y[y+18] + 9[y+18]=0
[y+9][y+18}
y= -9.................................3
y= -18......................................4
case 1 :
y= -9
x = 9-9=0
case 2:
y= -18
x= 9-18 = -9
