Answer:

Step-by-step explanation:

(a). A_{1} = x ( 2x + 1 ) = <em>2x² + x</em>

(b). A_{2} = 2( 2x + 1 )( 5x + 3 ) = <em>20x² + 22x + 6</em>

(c). A_{3} = 20x² + 22x + 6 - ( 2x² + x ) =

Can anybody help me?
makvit [3.9K]

Answer: x = 2

Steps: x + 3= 8x - 11

Subtract three form both sides: x + 3 - 3 = 8x - 11 - 3

Simplify: x = 8x - 14

Subtract 8x from both sides: x - 8x = 8x - 14 - 8x

Simplify:  -7x = -14

Divide both sides by negative seven: -7x ÷ -7   =   -14 ÷ -7

Simplify:  x = 2
