X(x - 2) = 4 [upon multiplying and moving the 4 becomes x² - 2x - 4 = 0] x(2x + 3) = 12 [upon multiplying and moving the 12 becomes 2x² - 3x - 12 = 0] 3x(x + 8) = -2 [upon multiplying and moving the -2 becomes 3x² + 24x + 2 = 0]
So, you divide 18 by 12 to get 1.5
but since you want the fraction, just reduce 18/12 as much as possible to get 3/2
Havent done this in years but i think it would just be 12
Answer:
12
Step-by-step explanation:
a² + b² = c²
a² + 9² = 15²
a² + 81 = 225
a² = 225 - 81
a² = 144
a = 12
Answer:
11.53 inches
Step-by-step explanation:
Given data
Diagonal = 19 inches
Height= 15.1 inches
Let us apply the Pythagoras theorem
D^2= H^2+W^2
substitute
19^2= 15.1^2+W^2
361=228.01+W^2
361-228.01=W^2
132.99= W^2
W=√132.99
W=11.53 inches
Hence the width is 11.53 inches
