Answer: 21
Step-by-step explanation:
Ok so first of all the numbers in the parentheses go first.
So 6 to the power of 2 (6^2) would be 6x6 which equals 36
50-36=14
After that you just keep rewriting the problem after every step.
Since the 3 is outside of the parentheses, you would multiply it with the 14
3x14=42
Finally 42÷ 2=21
3x (50 - 6^2) ÷ 2 =
3(14)÷ 2
42÷ 2= <u><em>21</em></u>

Step-by-step explanation:
Reflection on x-axis;
A(4,-5)=A'(4,5)
4/22 and 8/44 are equivalent
Answer:
1)-0.65 2) 28.8 3) 747.6
Step-by-step explanation:
- divide the numerator (-13) and the denominator (20)
- 32 x 90= 2880, divide 2880 by 100 equals to 28.8
3. multiply 12 by 62.3
I hope this helps!
The answer is 3.46 meters
You can get the answer by using the pythagorean theorem, since the ladder and the wall form a right triangle.
c^2 = a^2 + b^2
4^2 = 2^2 + b^2
16 = 4 + b^2
12 = b^2
b = sqrt(12) or 3.46 meters
