Step-by-step explanation:
(Ax² + Bx + C)²
= (Ax² + Bx + C)(Ax² + Bx + C)
= Ax⁴ + 2ABx³ + 2ACx² + 2BCx + C².
By Comparing Coefficients, we have:
A = 1
2AB = 6
2AC = 7
2BC = a
C² = b
Solving them we get A = 1, B = 3 and C = 3.5.
Therefore a = 2BC = 2(3)(3.5) = 21,
b = C² = (3.5)² = 12.25.
Yes acute angles are less then 90 degrees and obtuse are more. Right angles are 90 degrees
It's six

Year 1 5000 X 1.03 5150
Year 2 5150 X 1.03 5305
Year 3 5305 X 1.03 5464
Year 4 5464 X 1.03 5628
Year 5 5628 X 1.03 5796
Year 6 5796 X 1.03 5970
Year 7 5970 X 1.03 6149
Year 8 6149 X 1.03 6334
Year 9 6334 X 1.03 6524
Year 10 6524 X 1.03 6720
Here is the answer in the picture.
