16x^2 + 40x + 25
(4x)^2 + 2(4x)(5) + 5^2
(4x + 5)^2
The answer is: (4x + 5)^2.
2.3 x 8=18.4
18.4% of 17500 = 0.184 × 17500 = 3220
Answer:
x = 11
Step-by-step explanation:
Divide both sides of the equation by 4.
... (4x)/4 = (44)/4
... x = 11 . . . . simplify
_____
You could probably work this in 3rd grade in the form 4 × ___ = 44. In Algebra, we give a name (x) to the blank. It is the same problem. Your knowledge of number relationships (multiplication tables) still applies.
