PLEASE HELP ME PLSSSS I WILL MARK YOUR BRAINLIEST Kalie puts 6 stickers on her desk. Each sticker is 1/2 centimeters wide by 3/5

Damm [24]

Answer:

Total area: 9/5 square cm, or in decimal form 1.8 square cm

Step-by-step explanation:

Notice that each sticker is 1/2 cm by 3/5 cm, therefore they area is 1/2 times 3/5 = 3/10 square cm.

since she uses 6 of them, we need to multiply the area of each by 6 in order to get the total area:

6 times 3/10 = 18/10 square cm = 9/5 square cm or in decimal form 1.8 square cm

3+-√(-3)^2 - 4(5)(-1)

Alona [7]

Answer:

Step-by-step explanation:

Easy way to do this is step by step. Your quadratic, from your entry, must be

$5x^2-3x-1$ .

Step by step looks like this, one thing at a time:

$x=\frac{3+\sqrt{(-3)^2-4(5)(-1)} }{2(5)}$ becomes

$x=\frac{3+\sqrt{9-(-20)} }{10}$ becomes

$x=\frac{3+\sqrt{9+20} }{10}$

and this of course is

$x=\frac{3+\sqrt{29} }{10}$

Do the same with the subtraction sign to get the other solution.

If you're unsure of how to enter it into your calculator, do it step by step so you don't mess up the sign. If you enter it incorrectly, you could end up with an imaginary number when it should be real, or a real one that should be imaginary.

Just my advice as a high school math teacher.
