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
Answer:
Part A)
This quadratic expression can be factored by using the difference of squares pattern.
Part B) (5x+y) and (5x-y)
Step-by-step explanation:
Given:
25x^2-y^2
above polynomial can be factorize by using difference of squares formula
a2-b2=(a+b)(a-b)
25x^2-y^2= (5x-y)(5x+y)
so for part A)
correct option is This quadratic expression can be factored by using the difference of squares pattern.
Part B)
As factored above in part A,
the factors of given polynomial 25x^2-y^2 are (5x+y)(5x-y)
so for part B) correct options are (5x+y) and (5x-y) !
Answer: simplified expression is 3x+5
Explanation:
3(x+3)-4
-Distribute (multiply) 3 through parentheses to get
3x+9-4
-subtract the 9 and 4 to get
3x+5
That’s your solution to a simplified equation!!
25 weeks
178 + (3 x 25)
178 + 75 = 253
203 + (2 x 25)
203 + 50 = 253
Correct answer is 25 weeks.
