32 is my expression i think thats the correct answer
Answer:
Step-by-step explanation:
The letters are easy enough.
y^3 determines that 3 ys are needed. y^2 is taken in by the cubed.
x^4 determines that 4 xs are needed. x^3 is part of x^4 and you don't need any more xs
12 and 42 are the parts that will cause the problem. Factor them both into prime factors
12: 2 * 2 * 3
42: 2 * 3 * 7
You need two 2s.
You need one 3
You need one 7
LCD = 2 *2*3 * 7 = 84
Answer:
The value of height of the building h = 509.2 feet
Step-by-step explanation:
From the Δ A B C
⇒ h = y 
° ------- (1)
From Δ A B D
⇒ h = ( y + 300 ) 
° ------- (2)
Equation 1 = Equation 2
⇒ y ° = ( y + 300 ) °
⇒ 0.46 y = 0.36 y + 109.2
⇒ 0.1 y = 109.2
⇒ y = 1092 feet
Put this value of y in equation ( 1 ) we get,
⇒ h = 1092 × tan 25°
⇒ h = 509.2 feet
This is the value of height of the building.
