The answer is: " 9a² + 7a " .
_________________________________
Note: (3a)² + 7a = (3a)*(3a) + 7a = 9a² + 7a .

Question 4 is (1,2)
Question 5 is (1,0)
These are are definitely correct
Answer:
i think 1
remember like this: y=mx+b
m is slope
b is y intercept
Answer:
(4, 4)
Step-by-step explanation:
Coordinates of a point (x, y) after dilation with a scale factor k,
Rule to be followed,
(x, y) → k(x, y)
→ (kx, ky)
Coordinates of point T are (8, 8).
Dilation of the point T after dilation with a scale factor of
will be,
(8, 8) → 
→ (4, 4)
Therefore, coordinates of the image point B' will be (4, 4).
