Answer:
10^4
Step-by-step explanation:
Answer: -b - 9
Step-by-step explanation:
First, since the a cancel eachother out we are left with (4-b) + (-6-7)
Second, you want to add the -6 and -7 to get -13, so (4-b) - 13
Finally, add the 4 to the negative 13 to get (-b - 9)
Hope this helps.
Answer:
9) 4
10) p¹⁵/q⁹
Step-by-step explanation:
9)
As per the law of indices, (xᵃ)ᵇ=xᵃᵇ.
So divide 8 by 2 to get 4
10)
p(p⁻⁷q³)⁻²q⁻³
p(p¹⁴q⁻⁶)q⁻³ <em>(because (xᵃ)ᵇ=xᵃᵇ)</em>
pq⁻³(p¹⁴q⁻⁶)
p¹⁵q⁻⁹
p¹⁵/q⁹ <em>(because x⁻ᵃ =1 /xᵃ)</em>
x^2 + y^2 - 6x - 4y - 12 = 0
x^2 - 6x + y^2 - 4y = 12
x^2 - 6x + 9 + y^2 - 4y + 4 = 12 + 9 + 4
(x - 3)^2 + (y - 2)^2 = 25
Answer:
A. 46
Step-by-step explanation:
because IJ is 46 also and there both the same size.
