Answer:
Step-by-step explanation:
In exponent multiplication, if two numbers have same base, just add the exponents
In exponent division, if two numbers have same base, just subtract the exponents
Prime factorize 4 = 2*2 = 2²
4⁻¹ *(2³÷ 4⁻² )= (2²)⁻¹ * ( 2³÷ (2²)⁻²
= (2⁻²)* (2³ ÷2⁻⁴)
![= 2^{-2} * (2^{3-[-4]})\\\\= 2^{-2} * (2^{3+4})\\\\= 2^{-2} * 2^{7}\\\\= 2^{-2+7}\\\\= 2^{5}\\\\= 2 * 2 * 2 * 2 * 2\\\\= 32](https://tex.z-dn.net/?f=%3D%202%5E%7B-2%7D%20%2A%20%282%5E%7B3-%5B-4%5D%7D%29%5C%5C%5C%5C%3D%202%5E%7B-2%7D%20%2A%20%282%5E%7B3%2B4%7D%29%5C%5C%5C%5C%3D%202%5E%7B-2%7D%20%2A%202%5E%7B7%7D%5C%5C%5C%5C%3D%202%5E%7B-2%2B7%7D%5C%5C%5C%5C%3D%202%5E%7B5%7D%5C%5C%5C%5C%3D%202%20%2A%202%20%2A%202%20%2A%202%20%2A%202%5C%5C%5C%5C%3D%2032)
Its simple
the answer is ........
Neither Alex nor Jo are correct, because surface area is a 2-dimensional quantity, so it would be given in just square units, not linear nor cubic.
So the answer is D
Answer:
N(11 , 13)
Step-by-step explanation:
M(3,4) = (x,y)
A(-5, -5) = (x1,y1)
N ( )=(x2,y2)
using midpoint formula;
M(x,y)=(x1 + x2)/2 , (y1 + y2)/2
(3,4)= (-5 + x2)/2 , (-5 + y2)/2
Now;
3 = (-5+x2)/2 4 = (-5 +y2)/2
6 = -5 +x2 8 = -5 +y2
6+5 = x2 8+5=y2
x2=11 y2 = 13
2x² +5x -3
is your answer
hope this helps
