Answer:
36 ft²
Step-by-step explanation:
If BE = 3√2 ft, then the diagonal BD is 6√2 ft. The area of the square (as with any rhombus) is half the product of the diagonals. Since both diagonals are the same length, the area of the square is ...
area = 1/2·(6√2 ft)² = 36 ft²
The area of the square is 36 square feet.
_____
You may be expected to find the length of one side of the square using the Pythagorean theorem.
AB² = AE² + EB² . . . . . = the area of the square
AB² = (3√2 ft)² +(3√2 ft)² = 18 ft² + 18 ft²
AB² = 36 ft² . . . . . . . . . the area of the square
Answer:
Step-by-step explanation:
Given
Balls = 1 to 4
Required
Determine the probability of selecting ball numbered at least 2
Here, we'll assume that all numbers have the same probability.
The probability of each ball will be:
So:
Recall that
--- for each ball
So, the equation becomes
The formula for a triangular pyramid is 1/3AH. A is the area of the base. H is the height of the pyramid. So to find the area of a right triangle, you would use the formula (a x b)/2. So (10 x18)/2 is 90 inches^2. Now you can fill in the first formula. 1/3(90 x 14), which equals 420 inches^3. I hope you find this helpful (if correct.)

The reason i say this is because i don't really want to run into something that i don't know much about. I do know quite a bit about extinct animals more than i do aliens. So, that's my reasoning.

Answer:
C. x - 4
Step-by-step explanation:
The best way to do this is to first take out GCF
6(x² - x - 12)
Then we factor
6(x - 4)(x + 3)
We can now see our answer.
