D)true
they are right
In order to find out the answer to this question,, you must multiply 120 by
120 x
Now that we have the expression,, we can start to solve. The first step to solve this problem is to reduce the numbers with 10
12 x 6
Then we multiply the numbers together to see how many cards Kim gave to Maddy.
72
Finally,, we need to subtract 72 from 120 to find out how many cards are left in the box.
120 - 72 = 45
This means that Kim has 45 cards left in the box.
Let me know if you have any further questions

Answer:
or 2.738
Step-by-step explanation:
Let’s just look at the triangle on the top with the on the top and x on the bottom. (Basically the top half to the equilateral triangle)
There is a small square in the bottom right corner, which indicates that this triangle is a right triangle. This means that we can use the Pythagorean Theorem:
We know that \sqrt{10} is our hypotenuse, and therefore our c in our equation. Let’s say that x=a in our equation. Therefore we are left to find b. However, b is half the length of the side of the original equilateral triangle. An equilateral triangle means that all three sides are the same length. Therefore our side would also be \sqrt{10} units long. However we know that b is half of that value, so b= or
Plugging these values into the equation:
x^2+ (\frac{\sqrt{10} }{2})^{2}=\sqrt{10} ^{2}
This approximately equals 2.738
