For this case we must solve the following expression:
![-11 (-7)](https://tex.z-dn.net/?f=-11%20%28-7%29)
By law of multiplication of signs we have to:
![- * - =+\\- * + = -\\+ * - = -\\+ * + =+](https://tex.z-dn.net/?f=-%20%2A%20-%20%3D%2B%5C%5C-%20%2A%20%2B%20%3D%20-%5C%5C%2B%20%2A%20-%20%3D%20-%5C%5C%2B%20%2A%20%2B%20%3D%2B)
Also we must find the product of 11 and 7, this is equivalent to:
![11+ 11+ 11+ 11 +11+ 11 + 11 = 77](https://tex.z-dn.net/?f=11%2B%2011%2B%2011%2B%2011%20%2B11%2B%2011%20%2B%2011%20%3D%2077)
Thus, the result of the expression is +77.
Answer:
![-11 (-7) = 77](https://tex.z-dn.net/?f=-11%20%28-7%29%20%3D%2077)
Answer: option C) 12
The number of trials is the number of times that she performs the experiment, i.e. the number of times she rolles the cube..
The area is 84.
What I do it cut the polygon into something easier like a square and rectangle.
Rectangle: 6•12=72
Square: 4•3=12
Add them together and you have 84
Answer:
yes, yes, no
Step-by-step explanation:
1. L= i + 2j +k; P = -3i + j + k, line lies on one another at k
2. L =i + 2j + k and P = 6i -3j + k, the lines lie on one another at k
3. P = ai + bj and -2bi +2aj + (a+b) k
Answer:
10 cm
Step-by-step explanation:
The diagonal d divides the rectangle into 2 right triangles with legs 8 and 6 and hypotenuse d
Using Pythagoras' identity in one of the right triangles, then
d² = 8² + 6² = 64 + 36 = 100 ( take square root of both sides )
d =
= 10 cm
