3x^2 + 5x + 2
a = 3 , b = 5 , c = 2
Start by mulitplying a*c = 3 * 2 = 6
Now find two number that multiply to 6 and add up to b or 5
We could use 2 and 3 because ....
3 + 2 = 5
3 * 2 = 6
Now you rewrite....
3x^2 + 3x + 2x + 2
Now pull out common factors...
3x ( x + 1 ) + 2 ( x + 1)
The factors of this expression is ( 3x + 2 ) ( x + 1)
Answer:
x=3
Explanation: 11-5=6
6/2= 3
Plug 3 into the equation and you get 2x3+5=11 which 2x3=6 and 6+5=11
The expression: 4x² + 38x + 70 ; is a polynomial expression.

Answer:
555.94
Step-by-step explanation:
16 x 11 = 176/2
88
since there are two of the same triangle
88 x 2
176
11 is the radius
A = 
A = 3.14 ( pie is 3.14, if not then pi) x (11x11)
A = 3.14 x 121 (or 121)
A = 379.94
379.94 + 176 (or 121pi + 176)
555.94
