Answer:
The answer to your question is below
Step-by-step explanation:
Formula
Triangle's Area = 1/2 bh/2
Trapezoid's area = 1/2 (b1 + b2)h
Parallelogram's area = bh
Rectangle's area = bh
Considering the formulas, we can conclude that:
a) The first choice is true, both formulas have 1/2 in.
b) The second choice is also true, both equations are the same
c) The third choice is incorrect
d) This choice is correct, the bases are added,
e) This choice is incorrect, the sides are not added.
Answer:
Savings = 
- 
dollars.
Step-by-step explanation:
We are given that,
Juanita usually buys 50 pounds of mulch for $6.99.
That is, total cost of 254.7 pounds of mulch = dollars.
Now, since there is sale on the price of the mulch, we have,
Price of 50 pounds of mulch on sale = $5.99
Then, price of 254.7 pounds of mulch on sale = dollars.
Thus, the savings Juanita had = Original price of 254.7 pounds of mulch - Price of 254.7 pounds of mulch on sale.
Hence, savings = - dollars.

Answer:
You could just replace all the given possible values of k in the inequality and see which ones are solutions, but let's solve this in a more interesting way:
First, remember how the absolute value works:
IxI = x if x ≥ 0
IxI = -x if x ≤ 0
Then if we have something like:
IxI < B
We can rewrite this as
-B < x < B
Now let's answer the question, here we have the inequality:
I-k -2I < 18
Then we can rewrite this as:
-18 < (-k - 2) < 18
Now let's isolate k:
first, we can add 2 in the 3 parts of the inequality:
-18 + 2 < -k - 2 + 2 < 18 + 2
-16 < -k < 20
Now we can multiply all sides by -1, remember that this also changes the direction of the signs, then:
-1*-16 > -1*-k > -1*20
16 > k > -20
Then k can be any value between these two limits.
So the correct options (from the given ones) are:
k = -16
k = -8
k = 0
