Answer:
x = 24
y = 8√3
Step-by-step explanation:
This is a special right triangle with angle measures 30° 60° 90°
The side length that sees 90° is represented by 2a, the side length that sees angle 60° is represented by a√3 , and the side length that sees angle 30° is represented by a
16√3 ÷ 2 = 8√3 this is the value of y
8√3 × √3 = 24 this is the value of x
I’d say 21 tbh unless the sum is half of the brothers age then it would be 9
The coefficient of the x-term is -3. Add the square of half of that.
.. (-3/2)² = 9/4 . . . . . . the number you need to add.
x² -3x +9/4 = (x -3/2)²
_____
If the x² term has a coefficient other than 1, you need to factor that out first and deal with the remaining binomial. For example,
.. 2x² -6x = 2(x² -3x)
For this you would need to add 9/4 inside parentheses to get
.. 2(x² -3x +9/4) = 2(x -3/2)²
Of course, to keep the original value, you would need to subtract 2*(9/4) outside parentheses.
.. 2x² -6x = 2(x -3/2)² -9/2
Answer:
we would need the table that is above to answer this question.
Step-by-step explanation:
Answer: 17200
Explanation:
•Solve:
344 ÷ 20 × 10³
• Calculate 10 to the power of 3:
86/5 × 10³
•Express 86/5 × 1000:
86/5 × 1000
•Multiply 86 and 1000:
86 × 1000
—————-
5
•Divide 86000 by 5:
86000
———— = 17200
5
•Result:
17200
