When you use the quadratic formula, you’re making the function equal to 0. So we know that the zeros happen when x equals 2 and 4. So let’s try to think of a trinomial that factors to (x - 2)(x - 4). You could do FOIL to get x^2 - 6x + 8.

Now if you want to show your work, plug everything into the quadratic formula. Due to limitations on a phone, ill just write it out.

-b plus and minus the square root of b squared minus 4 times a times c, alllll over 2 times a

A woman bought a dress at a discount of 16 2/3%. If the woman paid $32.50, what was the original price of the dress?
Ostrovityanka [42]

Answer:

$39

Step-by-step explanation:

Let original price be x, so we need to subtract 16 2/3 % from that to get 32.50

So we can write:

100x-16\frac{2}{3}x=3250\\83\frac{1}{3}x=3250\\x=39

So basically, the original price was $39.

4.

A) 62.8 ft (Circumference)

B) 314 square ft (Area)

Step-by-step explanation:

3. Radius 7 cm

7*2=14 (Find the diameter)

14*3.14= 43.96 cm (Circumference)

7*7=49 (Find the square of radius)

49*3.14 = 153.86 square cm (Area)

4. Diameter: 20 ft

20*3.14 = 62.8 ft (Circumference)

20/2=10

10*10=100

100*3.14= 314 square ft (Area)
