Answer:
x = ±10
Step-by-step explanation:
4x² - 400 = 0
Add 400 to both sides
4x² = 400
Divide both sides by 4
x² = 100
Take the square root of both sides
x = ±10
The total number of strawberries on the farm is approximately 107
<h3>Total strawberries</h3>
The total number of strawberries on the farm can be solved by evaluating the expression (4 over 3)2 ⋅ 40.
Evaluation is the completion of a mathematical operation.
Number of strawberries on the farm = (4 over 3)2 ⋅ 40
= (4/3)2 × 40
= 8/3 × 40
= (8 × 40) / 3
= 320/3
= 106.6666666666666
Approximately,
Number of strawberries on the farm = 107

8 over 20 equals 6 over 15
First we should figure out how many times 2 goes into 69,(because each tile is 2 feet long) and I am going to do that by dividing 69 by 2. I got 34.5, so we can just say 35 to make it easier. So we now know we need 35 tiles, but they come in boxes of 6, so we will need to divide 35 by 6. It didn't make a full number (it was 5.833) but we need a full number of tiles so we will round up.
Our final number of how many boxes of tiles is 6.
Area is square units, so the new area would be the scale factor squared:
Scale factor is 2, so the area would increase by 2^2 = 4
The answer is B.4
