Factor the following:

2x2+9x+9

(2x+3)(x+3)

Step-by-step explanation:

Looking at this, you know that it must look something like

(? +3)(?+3) , because they must multiply to 9. The ?s must multiply to 2x^2, the most plausible values being 2x and x, ending us up with (2x+3)(x+3)

(x + 3) (2x + 3)

Step-by-step explanation:

2x^2+9x+9

2x^2 + 3x + 6x + 9

x(2x +3) + 3 (2x + 3)

(x + 3) (2x + 3)

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
