The width is 3m because 3*7 is 21m^2. Also they said the length is 4 more than the width (3+4=7)
N^3 + 1000
Steps
you have to apply the sum of cubes rule: x^3 + y^3 = (x + y)(x^2 - xy + y^2)
which is... n^3 + 1000 = (n + 10)(n^2 - 10n + 10^2)
= (n + 10)(n^2 - 10n + 10^2)
Simplify
= (n = 10)(n^2 - 10n + 100)
−3(1+x)=−3x+1
Step 1: Simplify both sides of the equation.
−3(1+x)=−3x+1
(−3)(1)+(-3)(X)=-3x+1
(Distribute)
−3+ −3x=−3x+1
−3x−3=−3x+1
Step 2: Add 3x to both sides.
−3x−3+3x=-3x+1+3x
−3=1
Step 3: Add 3 to both sides.
−3+3=1+3
0=4
Answer:
There are no solutions.
D, “it is one-half the area of a rectangle of length 2 units and width 4 units.”
HOPE THIS HELPS!!!
