Step-by-step explanation:
First you must simplify the equation:
subtract 1 from both sides:
than divide both sides by -3, which switches the inequality sign:
This inequality means that all values of x greater than -2 work for the equation. because it is not 
, -2 is not included, so there will be a hollow circle there. than the inequality will have a line from that dot to the right so that all values of x that work for the inequality are on that line.
Base = 2 inches
Height = 8 inches
Area = b x h = 2 x 8 = 16
Perimeter = 2(8) + 2(2) = 20 inches
Answer:
Belinda is correct
Step-by-step explanation:
A is 115°
180-45 = 135
135÷ 2=67.5
100-67.5 = 32.5
32.5*2 =65
180-65= 115°
<span>The equation x^2 - 36 = 5x is a quadratic equation and can be solved thus:
x^2 - 36 = 5x
x^2 - 5x - 36 = 0
x^2 + 4x - 9x - 36 = 0
x(x + 4) - 9(x + 4) = 0
(x - 9)(x + 4) = 0
x - 9 = 0 or x + 4 = 0
x = 9 or x = -4
Therefore, the positive solution of x^2 - 36 = 5x? is 9.</span>
