Answer:
Step-by-step explanation:
As it is a second order equation, it means that it has two possible answers and they are
and
.
The famous quadratic formula for solving any second order equation is the following:

Where a is the coefficient of
, b is the coefficient of x, and c is the free term. In other words,

as the equation should be in the following form:

Therefore the possible answer should be the following,


by dividing the numerator and denominator by 2, we can deduce the following,
Let a and b represent the heights of the corresponding buildings (in meters).
... a = b +271 . . . . . . . a is 271 meters taller than b
... 2b -a = 211 . . . . . . if a is subtracted from twice b, the result is 211
Use the expression for a in the first equation to substitute for a in the second.
... 2b - (b+271) = 211
... b = 482 . . . . . . . . . . . simplify and add 271
... a = b +271 = 753
Building a is 753 meters tall; building b is 482 meters tall.
Answer:
A. 3h – 9/2 B.
Step-by-step explanation:
DBH make a triangle.
The three inside angles of a triangle need to equal 180
H = 180 - B - D
H = 180 - 39 - 36 = 105
H and X make a straight line that equals 180 degrees
X = 180 - H
X = 180 - 105 = 75 degrees.
