Step-by-step explanation:
Y= x - 2. Y = 3x + 5
Putting value of y
x - 2 = 3x + 5
-2 - 5 = 3x - x
-7 = 2x
-7/2 = x
Putting value of x
Y = 3(-7/2) + 5
Y = - 10.5 + 5
Y = - 5.5
So I think the rule is that you divide two exponents with the same base, you keep the base and subtract the powers.

Exact dimensions:



Approximate dimensions:



Step-by-step explanation:
Let's assume width of rectangle is w ft
The length of a rectangular flower bed is 2ft longer than the width
so,
length =w+2

now, we can find area

now, we can plug it


we are given area =6
so, we can set it equal
and then we can solve for w


we can use quadratic formula


now, we can compare and find a,b and c
a=1 , b=2 , c=-6


we know that dimension can never be negative
so, we will only consider positive value
