Answer:
Length = 34 and Width = 30
Step-by-step explanation:
This is a simple system of equation that is mainly solved using substitution, so keep in mind the following key points:
- Rectangle's Perimeter is 128 ft.
- "the garden is 4 feet longer than it is wide," this simply means that the Length is 4 feet longer than the Width: which algebraically translates to
- Perimeter formula for Rectangle is
First, we find the Width by plugging the given values in the formula:
All we did here was substituting 4 + W for L to find the Width.
Now, to find the Length we plug in the value of W and solve for L:
Tip: always sketch a rough geometrical diagram of word problems, it helps. (Refer to the diagram attached)

The probability is 0.336.
To solve this, we need Binomial Probability equation for Repeated Trials.
P = nCr (p)^r (q)^(n-r)
where P = probability (unknown)
n = number of trials (8)
r = number of successes (1)
p = probability of success (.20)
q = probability of failure (0.80)
P = 8C1 (.20)^1 (.80)^7
= 0.336
Answer:
This would be a 90 degree rotation in a counter clockwise fashion.
Step-by-step explanation:
You can tell this because in a 90 degree shift, the values switch terms. Also, one of the terms will change the sign.
