Answer:
Step-by-step explanation:
<u>Area formula:</u>
<u>The height is:</u>
- h = (x + 2)sin 45° = √2(x + 2)/2
<u>Substitute the area value an set an equation:</u>
- 4√2 = (2x - 3)√2(x + 2)/2
- (2x - 3)(x + 2) = 8
- 2x² + x - 6 = 8
- 2x² + x - 14 = 0
- D = 1 + 4*2*14 = 113
- x = (-1 + √113)/4 = 2.41 (rounded)
Note. the second root ignored as negative
Answer: The answer would be A. Or if that is what you are asking.
Step-by-step explanation:
When you multiply decimals, you multiply like how you would for any other set of numbers. (It doesn't matter if you line the decimal points up or not.)
The only difference between multiplying normal numbers and decimals is the decimal point. How many digits there are to the right of the decimal point is how many times you move the decimal point for the new number to the left.
In the decimals 5.15 and 0.3, there are three digits to the right of the decimal in all, so, when you work this problem and come out with 1545, you move the decimal point to the left three times.
1^545
So the decimal point goes right between the 1 and the 5.

Count the distances that a tortoise and a hare completed.
1. Tortoise. The speed of the tortoise is constant and equal to 4 miles per hour. Then in 4 hours the tortoise completed 4·4=16 miles. It has a 10-mile lead, then the distance that the tortoise completed in total is 10+16=26 miles.
2. Hare. The speed of the hare is constant and equal to 14 miles per hour. But the hare stops for a two-hour nap, then the hare was 4-2=2 hours running. Then the distance that hare completed is 14·2=28 miles.
3. As you can see the hare gets farther than tortoise 2 miles.
