Answer:
(x+3)(x+4)
Step-by-step explanation:
(x+3)(x+4)
this is because your two numbers after x should add to 7 and multiply to 12.
hope that makes sense!
Answer: One solution, I think
Step-by-step explanation: If you combine like terms, x=4
Answer:
13/20
Step-by-step explanation:
To get this answer, you add 7 and 13 together and you get 20. Then you put 13 over 20 and that becomes 13/20. Since 13/20 cannot be simplified any further, that is your final answer.
Hope this helps, have a great day/night!

Answer:
x=5
Step-by-step explanation:
Since this is a right triangle, we can use the pythagorean theorem
a^2 + b^2 = c^2
x^2+ ( 2x+2)^2 = (2x+3)^2
FOIL the squared terms
x^2 +(4x^2 + 4x+4x+4) = 4x^2 + 6x+6x +9
Combine like terms
5x^2+8x +4 = 4x^2 +12x +9
Subtract 4x^2 +12x +9 from each side
5x^2+8x +4 -4x^2 -12x -9= 4x^2 +12x +9-4x^2 -12x -9
x^2 -4x -5 =0
Factor
(x-5) (x+1) = 0
Using the zero product property
x=5 x=-1
But x cannot be negative or we would have negative length
x=5
