Q+B=13. When B+3=0
You have 2 separate equations.
First solve the 2nd equation for B:
B +3 = 0
Subtract 3 from both sides:
B +3 - 3 = 0-3
Simplify:
B = -3
Now we have a value for B, we can replace b with -3 in the first equation and solve for Q:
Q + -3 = 13
Add 3 to each side:
Q + -3 + 3 = 13+3
Simplify:
Q = 16
So you have Q = 16 and B = -3

12.03 feet is the right answer.
Answer:
Area - 6 unit^2 Perimeter - 10 units
Step-by-step explanation:
The shaded figure is 3 units long and 2 units high.
L = 3 W = 2
A = LW
A = 3 x 2 = 6 unit^2
Perimeter = 2L + 2W
P = 2(3) + 2(2)
P = 6 + 4 = 10 units
Answer:

Step-by-step explanation:
A standard die has six numbers (1 through 6). That means there is a 1/6 probability of rolling any one number. There is a 3/6 probability of rolling one of the selected numbers which simplifies to 1/2 or 0.50
