Answer:
the answer is $120
Step-by-step explanation:
60+60 is 120
-9 -4x = 7
add 9 to both sides in order to isolate the x
-4x = 16
divide by -4
x = -4
The polynomial is not factorable, so use the quadratic formula.
y^2 + 8y + 19 = 0
x = (-b +- sqrt(b^2 - 4ac))/(2a)
x = (-8 +- sqrt(8^2 - 4(1)(19))/(2 * 1)
x = (-8 +- sqrt(64 - 76))/2
x = (-8 +- sqrt(-12))/2
If you have not learned imaginary/complex numbers, then the answer is "No solution" since there is no real number solution.
If you have learned imaginary/complex numbers, then we'll continue.
x = (-8 +- 2i sqrt(3))/2
x = -4 +- i sqrt(3)

b = base length (of triangle)
h = height of triangle
s = side length of triangle
l = length of rectangle
Answer:
12.8, 11.6, 10.4, 9.2, 8.0, 6.8, 5.6
3, 1.5, 0.75, 0.375, 0.1875, 0.09375, 0.046875
Step-by-step explanation:
The first one is arithmetic as the pattern is deducting 1.2, second one is geometric as it is dividing 2.
