Standard form is (y=x+n) *n=number* y=-3x+2
2x² - 3x - 20
40
2 20
4 10
5 8
2x² - 8x 5x - 20
2x(x - 4) 5(x - 4)
(2x + 5) (x - 4)
2x + 5 = 0 x - 4 = 0
2x = -5 x = 4
x = -5/2
C) x = -2.5 and 4
It just happens that tan 14 degrees is about 0.25 or 1/4. According to my calculator, it's actaull 0.249.
Now try finding tan 76 degrees to approx. the same level of accuracy.
tan 76 deg = (via calculator) 4.0108. this could be re-written as 4 or 4.1.
Answer: 
Step-by-step explanation:
We just multiply the values on the edges like we are finding the area of a square, L * L = area.
4x * 5x = 20x^2
4x * 8 = 32x
3 * 8 = 24
3 * 5x = 15x
Next add the answers together
20x^2 + 47x + 24
