Answer:
1. 8
2. 247.25
3. 4.5
4. 276
Explanation:
To solve this problems we must consider the length and width of the Vegetable Garden.
L = 3x+2
W = x+5
1. 8
First place the area of the garden (for this question: 338) equivalent to the area of the garden equation you should have figured out in the previous question.
3x^2 + 17x + 10 = 338
Next solve for x. You will get a - and a + answer, because we are trying to find the length we will only use the + value.
3x^2 + 17x + 10 - 10 = 338 - 10
3x^2 + 17x = 328
3x^2 + 17x - 328 = 0
(Solve using quadratic formula or calculator)
x = 8
2. 247.25
First replace x with the length of the tomato patch:
3(6.5)^2 + 17(6.5) + 10
and solve.
3(6.5)^2 + 17(6.5) + 10 = 247.25
3. 4.5
Complete the same steps as number 1 but place the area 147.25 equivalent to the garden area expression.
3x^2 + 17x + 10 = 147.25
3x^2 + 17x + 10 - 10 = 147.25 - 10
3x^2 + 17x = 137.25
3x^2 + 17x - 137.25 = 0
(Solve using quadratic formula or calculator)
x = 4.5
4. 276
Complete the same steps as number 2 but replace x with 7
3(7)^2 + 17(7) + 10
and solve.
3(7)^2 + 17(7) + 10 = 276
Hope this helps!
