Answer:
4a^4·b^5
Step-by-step explanation:
The applicable rule of exponents is ...
(x^a)(x^b) = x^(a+b)
The commutative and associative properties of multiplication apply, so we can write the expression as ...
4·(a^3·a)·(b^2·b^3) = 4·a^(3+1)·b^(2+3) = 4·a^4·b^5
First find x and y.
Solve system of equations by elimination.
3x-y=3
+(-x+y=3)
---------------
2x=6
x=3
Now plug in x into one of the equations to find y.
-3+y=3
y=6
xy=3x6=18
Answer:
99 m
Step-by-step explanation:
The 10 covers required ...
(10 covers) × (3 m/cover) = 30 m
So the amount remaining is ...
150 m - 30 m - 21 m = 99 m
Lee has 99 m of the fabric left.
