First subtract h from h to get - 2h
Then add 19 to both sides leaving you with
-2h = -32
Then divide by -2 on both sides
H = 16
Answer:
The area of square in terms of x = 16x² -24x + 9
Step-by-step explanation:
It is stated in the question that the length of a square = 4x - 3
Formula to find the area of the square is
Area = length²
Area = ( 4x - 3 )²
by using ( a - b )² = a² + b² - 2ab
here a = 4x and b = -3
So,
(4x)² + (-3)² - 2(4x)(3)
16x² + 9 - 2(12x)
16x² + 9 - 24x
16x² -24x + 9
The area of square in terms of x = 16x² -24x + 9
its true because -1 to even power is positive, -1 to odd power is negative
The answer is D.
Angle U and S are both 110 degrees.
Adding the three known angles subtract from 360 leaves only 20 degrees for angle T.
