Answer:
Step-by-step explanation:
Multiply 3 times 4x which gives you 12. Multiply 3 times 2 which gives you 6. Your final answer is 12x+6
The standard form of a circle is:
(x-h)^2+(y-k)^2=r^2, where r=radius and (h,k) is the center of the circle.
We are told that r=6 and the center is (10,-6) so
(x-10)^2+(y+6)^2=36
<span>For this question you are looking for the value of K. The question is asking what number multiplied with 8 and added with 12 equals 48. So the equation is:
12+8(K)=48
To solve the problem you need to balance the equation by doing the opposite of the equation to the answer until only K remains.
We start with the 12. The equation wants us to add 12 so we subtract it from both sides instead and get the new equation:
12+8(K)=48-12 : 8(K)=36
Now we need to get rid of the 8. The equation wants us to multiply by 8 so we divide it from both sides instead and get the new equation:
K=36/8 : K=4.5
So the answer is K=4.5. Now just to make sure we test the equation with the answer.
12+(8x4.5)=48
12+36=48
48=48
Since the two match we have confirmed that K does indeed equal 4.5.</span>
