Xsquare + 10x + 16 equals 0

Mathematics
1 answer:
inn [45]2 years ago
7 0
X^2+10x+16=0

First, you find factors of 16.
1 x 16
2 x 8
4 x 4

Next, you find which of the factor pairs adds up to 10 (from the 10x). In this case, 2 x 8 because 2 times 8 is 16 and 2 plus 8 is 10.

Then, the equation will be written out as: (x+2) (x+8). Take those two equations and set them equal to 0, and then solve.

x+2=0
-2 -2
x=-2

x+8=0
-8 -8
x=-8

So, your answers are x=-2 and x=-8. You can check by plugging in those two numbers as x.

Help Please! Lots of points

Assume that the radius of the circle is 1.


The diagonal of the square is 2. By the Pythagorean Theorem, the side of the square of a right triangle will be 2/sqrt(2).


Finally, the ratio of the square to the circle, in area, will be


(2/sqrt(2))^2 : pi*(1)^2 = 2 : pi


We can conclude that the white area is about 35%.

A slide has a diagonal of 10 feet and covers a distance of 8 feet across the ground. How many feet high is the slide at its high
Tasya [4]

So, this creates a triangle once again. If we imagine a slide, the slide itself would be the hypotenuse of the triangle, then if there's a ladder leading up to the slide, that would be the vertical length we're looking for. The feet across the ground would be the distance from the bottom of the slide to the bottom of the ladder.

We can use the Pythagorean theorem to find the missing side length, as this would create a right triangle. | 8^2 + b^2 = 10^2 | 64 + b^2 = 100 | b^2 = 36 | b = 6 feet | The slide is 6 feet high at its highest point.

I payed for a subsciption my bank has already been debted but it wont let me use it. why not?
ANEK [815]

Answer:

If your payment didn’t go through, change your preferred payment method/add another payment method.

For example, if your preferred payment method is your bank account, we'll always try to use your bank account first for payments. If there's an issue with your bank account, you can change your preferred payment method to a different one, such as a debit or credit card. If you only have a card registered on your account, try adding and confirming a bank account.

Step-by-step explanation:

Daniel works at a nearby electronics store. He makes a commission of 15% on everything she cells. If he sells a laptop for $293,
Bezzdna [24]

Hi there!

So here's the important information we know:

He makes 15% comission on everything he sells

He sells a laptop for $293


To find out how much money Daniel makes in comission for the laptop, you need to calculate 15% of $293, which is the same thing as multiplying 15% by $293 :

15% × 293 = $

0.15 × 293 = $

43,95 = $


So your answer is: If Daniel sells a laptop for $293, he makes a comission of $43,95.


There you go! I really hope this helped, if there's anything just let me know! :)
