Answer:
Area: 12x + 66
Perimeter: 2x + 35
Step-by-step explanation:
Area is the base and the height multiplied, 12(x) + 12(5.5), which is simplified to 12x + 66.
Perimeter is all the sides added together, (x + 5.5) + (x + 5.5) + 12 + 12, which is grouped to be 2x + 11 + 24, then simplified to 2x + 35.
Answer:
Slope: 7
Step-by-step explanation:
y=mx+b

Answer:{d,t}={187, 17/2}
Step by step explanation :
System of Linear Equations entered :
[1] d - 18t = 34
[2] d - 22t = 0
Graphic Representation of the Equations :
-18t + d = 34 -22t + d
Solve by Substitution :
// Solve equation [2] for the variable d
[2] d = 22t
// Plug this in for variable d in equation [1]
[1] (22t) - 18t = 34
[1] 4t = 34
// Solve equation [1] for the variable t
[1] 4t = 34
[1] t = 17/2
// By now we know this much :
d = 22t
t = 17/2
// Use the t value to solve for d
d = 22(17/2) = 187
Im assuming B because a 2/3 chance means most likely, not impossible or certain
