Answer:
AB = 35
Step-by-step explanation:
For the value of variable z....;
;Perimetre = 132
; 132 = 2(4z + 3) + 2(5z)
; 132 = 8z + 6 + 10z
; 132 - 6 = 8z + 10z
; 126 = 18z
;the value of...z = 7
Therefore the value of length AB;
AB = 5z...then substitute the value of z into the length of AB
; AB = 5(7)
;AB = 35
The answer is (8,-1)
Happy studying!
Answer: 135
Step-by-step explanation: All you need to do is 180-45=135.
Given:
Consider the number as <em>x</em>.
The objective is to represent algebraic expression for, 2 is subtracted from the square of a number.
Explanation:
Since the number is given as <em>x</em>, the square of the number can be represented as,

Now, subtract 2 from the above expression,

Hence, the required expression is x²-2.
Not much to work with, I need the value of n .
