Answer:
x<《-4,12》
Step-by-step explanation:
inequalities:
x-4<8, x-4>0
-(x-4)<8, x-4-<0
intersections:
x<12, x>4
x>-4, x<4
x<[4,12》
x<《-4,4》
x<《-4,12》
To convert 1.07 to a fraction, multiply it by 100.
1.07 * 100 = 107
So the percent equivalent of 1.07 is 107%.
Just put 1.07 over 100 to turn it into a fraction.
107/100 would be the fraction equivalent.
Answer:
(a is size of side of triangle)
the perimeter of equilateral triangle =3a
or, 36=3a
Thus, a = 13cm
area of equilateral triangle
=√3/4*(a^2 )
=√3/4*(13^2)
=73cm^2
Answer:
x = - 4 ± 2
Step-by-step explanation:
Given
f(x) = x² + 8x + 4
To find the zeros let f(x) = 0, that is
x² + 8x + 4 = 0 ( subtract 4 from both sides )
x² + 8x = - 4
To solve using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(4)x + 16 = - 4 + 16
(x + 4)² = 12 ( take the square root of both sides )
x + 4 = ± 
= ± 2 ( subtract 4 from both sides )
x = - 4 ± 2
Thus the zeros are
x = - 4 - 2 and x = - 4 + 2
Answer:
x=2
Step-by-step explanation:
