Bailey writes the expression g2 + 14g + 40 to represent the area of a planned school garden in square feet. If g = 5, what are t
he dimensions of the school garden? 20 feet by 2 feet 10 feet by 4 feet 12 feet by 7 feet 15 feet by 9 feet
2 answers:
g^2 14g+40
replace g with 5
5^2 +14(5) +40 = 25 + 70 +40 = 135 square feet
Area =L x W
using your choices multiply 15 x 9 = 135
so answer is 15 feet by 9 feet
To solve this, you need to plug in your solution to your variable.
g² + 14g + 40
5² + 14(5) + 40
25 + 70 + 40
So, your area would be 135.
Out of your 4 options, you need to find out which dimensions create 130.
20 × 2 = 40
4 × 12 = 48
12 × 7 = 84
15 × 9 = 135
Your dimensions are 15ft by 9ft :)
Hope this helps!
