L=2w-3
w(2w-3)=54
2w²- 3w-54=0
A= 2 , B= -3, C= -54
sub values into quadratic formula

Final answer: you will be given 2 answers 6 and -4.5. -4.5 is rejected since a negative value cannot represent length because that just doesn't make sense.
w=6
Check:
L=2w-3
=2(6)-3
=12-3
=9
9*6=54
Therefore the dimensions of the photograph are 6 cm by 9 cm
If I understand it correctly then its complementary angle will be 115˚, because 180-65=115.

Answer:
y = 15
Step-by-step explanation:
x + y + z = 45 → (1)
Given
y = (x + z)
Multiply both sides by 2 to clear the fraction
2y = x + z ← substitute into (1)
2y + y = 45
3y = 45 ( divide both sides by 3 )
y = 15
