<h3>
Answer: Sometimes true</h3>
========================================================
Explanation:
-8+d is positive only when d > 8
Here's why
-8+d > 0
-8+d+8 > 0+8 .... add 8 to both sides
d > 8
So if Jessica said "d is greater than 8", then her claim would always be correct.
However, her claim is sometimes true.
Two counter examples could be when d = 1 and d = 2.
If d = 1, then -8+d = -8+1 = -7 which isn't positive.
If d = 2, then -8+d = -8+2 = -6 which also isn't positive.
Basically if d is anything smaller than 8, then you'll have -8+d be negative.
If d is something larger than 8, say d = 9, then -8+d = -8+9 = 1 which is finally positive.
43
48 - 27(since they left) + 22(since they joined) = 43
Consider the given table.
- The first row represents first term (first brackets):
+x+x+x-1=3x-1
- The first column represents second term (second brackets):
+x-1=x-1
- The product of (3x-1) and (x-1) is equal to the sum of all remaining terms in this table:
+x²+x²+x²-x-x-x-x+1=3x²-4x+1.
Therefore, 3x²-4x+1=(3x-1)(x-1).
Answer: correct choice is C.

Answer:
Yes
Step-by-step explanation:
4'9" is 57 inches. Jannet is taller than that, so should go without a booster seat.
___
<em>Feet to Inches</em>
1 foot is 12 inches, so 4 feet is 4×12 = 48 inches. Adding 9 inches to that gives ...
... 4' 9" = 57 inches
