Answer: 7^11</h3>
Explanation:
The rule is
a^b*a^c = a^(b+c)
Note how each base is the same (both 'a' each time). The rule wouldnt work if the bases were different.
So,
a^b*a^c = a^(b+c)
7^6 * 7^5 = 7^(6+5)
7^6 * 7^5 = 7^11
In short, you just add the exponents.
Keep in mind that the base stays at 7 the whole time. It might be tempting to do 7*7 = 49, but that would be incorrect.
If A=pir2
and we know A = 16pi
All we need to do is find the square root of pi, which is 4. 4*4 = 16.
So, the radius of the circle is 4.
I will Say its 250% Cause 127.5 is 250% of 51
Answer: Subtraction property of equality.
Step-by-step explanation:
n + 9 = -3
You are trying to move 9 from one side to the other. To do that, you have to do the <em>inverse operation</em> and <u>subtract</u> nine from both sides. Your result would be n = -12.
