I dont know if you wanted the steps but:
x^2-4x-6=0
plug it into the equation:
![[tex] \frac{4\sqrt{40}}{2}](https://tex.z-dn.net/?f=%20%5Btex%5D%20%5Cfrac%7B4%5Csqrt%7B40%7D%7D%7B2%7D%20)
[/tex]
x^2-4/3x+1/3 x=1 , x= 1/3
2x^2-3x+1=0 x=1 , x=1/2
6x^2+12x=-5
add the 5 to both sides
6x²+12x+5=0 plug the problem into the equation
x=
x=[
x=
x=
x=
The answer is 38,016. You have to multiply 4800 by 6 which equals 28,800. then multiple 0.32 times 4800 which equals 1538. multiply 1538 by 6 which equals 9,216 and then add 28,800 which equals it to 38,016.
<u>Answer</u>
24 square units
<u>Explanation</u>
The formula for getting the area of a trapezium is
Area = 1/2 h(a+b0
where h ⇒ perpendicular height
a and b ⇒ length of the parallel sides.
h = 2 - -2 = 4 units
a = 5 - -3 = 8 units
b = 3 - -1 = 4 units
Area = 1/2 × 4(8+4)
= 2×12
= 24 square units.
If the item is 30% off, the new price is 0.7p because we want to know how much 70% of the original price was.
