Step-by-step explanation:
The end of the equation has to equal 0, so c can not be -6 but instead -12.
They forgot about the 4 +/- the square root of 40 in the last step.
Answer:
C. 72
Step-by-step explanation:
your are given the adjacent length of 2.4 cm and the hypotenuse of 7.8cm
so we know cos = adjacent/ hypotenuse
so to find the angle of cos you use the inverse of cos^-1(2.4/7.8)
after typing into calculator you should get about 72
Step-by-step explanation:
now,
a = 4, b = -5, c = -5
Y = x + 13
y + x ≥ 103
x + 13 + x ≥ 103
Inequality is:
2 x + 13 ≥ 103
2 x ≥ 103 - 13
2 x ≥ 90
x ≥ 90 : 2
x ≥ 45
