width = w
length = 2w - 5
Perimeter = 26
The formula for perimeter is:
P = l + l + w + w
Plug in corresponding values into this equation...
26 = (2w - 5) + (2w - 5) + w + w
Now you must solve for w
26 = 2w - 5 + 2w - 5 + w + w
Combine like terms
26 = 2w - 5 + 2w - 5 + w + w
26 = 6w - 5 - 5
26 = 6w - 10
Bring -10 to the other side by adding it to both sides
26 + 10 = 6w + (-10 + 10)
36 = 6w + 0
36 = 6w
Isolate w by dividing 6 to both sides
36/6 = 6w/6
6 = w
Width is 6 cm
To find length plug 6 in for w in the equation 2w - 5
2(6) - 5
12 - 5
7
Length is 7 cm

Answer:
The value of E [Z] is 0.50.
Step-by-step explanation:
The expected value is computed using the formula:
Denote the three dices as follows:
X₁ = a four-sided die
X₂ = a six-sided die
X₃ = a 12-sided die
Define the indicator variables as follows:
The probability of rolling a 4 in the three dices are as follows:
Compute the value of E [Z] as follows:
Thus, the value of E [Z] is 0.50.
It should be acute because if A and B are complementary then B and A added together should be 90 so 90-30=60 and 60 would be an acute angle
