Can anyone good in math me i’m in a hurry : (

First lets consider the regular numbers here. 15 + 24. That gives us 39. Next we consider the variables. There's 0 a's in the first part, and 1 in the second part. So you simply get 1a added on top of the 39. Next, the x variable. There's one on each part, so just add them together to get x^2 (Note that you must do it this way rather than getting 2x since you're only adding x's, so when adding/subtracting variables on its own, its expressed as an exponent). With all this in mind, you'd get answer A

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
