(x+3) (x+1) = x^2 +19

with steps

( x + 3 )( x + 1 ) = x^2 + 19

x^2 + ( 1 + 3 )x + ( 1 × 3 ) = x^2 + 19

x^2 + 4x + 3 = x^2 + 19

Subtract both sides x^2

x^2 - x^2 + 4x + 3 = x^2 - x^2 + 19

0 + 4x + 3 = 0 + 19

4x + 3 = 19

Subtract both sides 3

4x + 3 - 3 = 19 - 3

4x + 0 = 16

4x = 16

Divide both sides by 4

4x ÷ 4 = 16 ÷ 4

x = 4

( 4 + 3 )( 4 + 1 ) = 4^2 + 19

( 7 )( 5 ) = 16 + 19

35 = 35

Thus we found the correct value of x which is 4 .

step-by-step explanation:

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}
