Answer:
x=a, 2a −(1+a 2 )
Step-by-step explanation:
Given, (1−a 2 )(x+a)−2a(1−x 2 )=0 x+a−a 2 x−a 3 −2a+2ax 2 =0 x−a−a 2 x−a 3 +2ax 2 =0 2ax 2 +x(1−a 2 )−(a+a 3 )=0 By using formula, we have x= 2(2a) −(1−a 2 )± (1−a 2 ) 2 −4(2a)[−(a+a 3 )] = 4a −(1−a 2 )± (1+3a 2 ) 2 = 4a −(1−a 2 )±(1+3a 2 ) = 4a −1+a 2 +1+3a 2 ; 4a −1+a 2 −1−3a 2 = 4a 4a 2 ; 4a −2−2a 2 =a; 2a −(1+a 2 )
Answer:
x = 2.5
Step-by-step explanation:
x = 5 - x
x + x = 5 - x + x
2x = 5
2x/2 = 5/2
x = 2.5
Hi,
First we need to find 3.75/0.25, then multiply that with 1(same number),since 0.25 inch =1 mile
3.75/0.25=15
That means length=15 miles
Find width in the same way.
2.25/0.25=9
Width=9 miles
a=l*b
a=15*9
a=135 sq. miles
Hope this helps you.
