Answer:
Step-by-step explanation:
55% of 48 = 26.4
0%-------------------------------------60%------------100%
0 26.4
60x1.6~=100

Answer:
a=36
Step-by-step explanation:
because look 0a=a
0a=36
a=36
The equivalent expression is option A) 12(l+2a)
<u>Step-by-step explanation</u>:
- The expression for total cost = 12l+24a
- Taking 12 as common from all the terms in the expression,
we get, 12 (l+2a)
Therefore, The equivalent expression of 12l+24a is 12(l+2a).
4x^2 + 20x + 25 = 0
4x^2 + 10x + 10x + 25 = 0
2x(2x + 5) + 5(2x + 5) = 0
(2x + 5)(2x + 5) = 0
