We know that the area of a rectangle can be written as: length x width
so:
l x (1/5) = 9/20
9/20 x 5/1 = 45/20, which can be reduced to 9/4
So the length is 9/4 miles
Like terms have the same variables and exponents. Constants are also like terms.
The given expression is
Зу + 3y + 5+ 7x^3 - у - 6 - 7x^3
By combining like terms, it becomes
7x^3 - 7x^3 + 3y + 3y - y + 5 - 6
= 5y - 1
(3,7) becomes (3,-7) when reflected across the x axis.
15 624/1000 is it supposed to be sipplified?
