Your answer would be 4:$7.20 because 2027-2002 is 25 years and 0.24(25)+1.20 is $7.20
Answer:
{ - 2, 10 }
Step-by-step explanation:
Given
x² - 8x = 20
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 4)x + 16 = 20 + 16, that is
(x - 4)² = 36 ( take the square root of both sides )
x - 4 = ± = ± 6 ( add 4 to both sides )
x = 4 ± 6
Thus
x = 4 - 6 = - 2
x = 4 + 6 = 10
Answer:
See below.
Step-by-step explanation:
The 3 angles of all triangles add up to 180 degrees.
An isosceles triangle has 2 of its angles equal.
So if one of the angles is 130 degrees then there cant be another one of 130 degrees as that would make 260 degrees.
So the other 2 angles are equal and their measure is (180 - 130) / 2
= 50 / 2
= 25 degrees.
The 2 equal angles are both 25 degrees.
