Answer:
P = 2x² + 8x - 30
P = 12 (if x = 3)
Step-by-step explanation:
Perimeter Formula: 2l + 2w
Step 1: Find perimeter
2(2x² - 16) + 2(-x² + 4x + 1)
4x² - 32 - 2x² + 8x + 2
2x² + 8x - 30
Step 2: Plug in x = 3
2(3)² + 8(3) -30
18 + 24 - 30
42 - 30
12
Answer:10 people
Step-by-step explanation:
7 times less showed up so, 70 divided by 7 is 10. 10 guests attended.
The James family expected 70 guests for their party, but 7 times fewer showed up. By dividing the expected guest number by 7 (70 ÷ 7), we find that 10 guests attended the party.
The James family expected 70 guests to attend their independent day party. However, 7 times fewer guests showed up than expected. We can calculate this by dividing the expected number of guests by 7.
Step 1: Identify the total number of guests expected which is 70.
Step 2: Divide the expected number of guests by 7. This is because the actual number of attendees was 7 times fewer than the expected.
Step 3: Perform the division: 70 ÷ 7 = 10.
So, 10 guests attended the independent day party hosted by the James family.

b) 2w (squared) -19w
d) 3w-19
The expression that represents the area of the classroom floor is 2w -19w
'A plane figure with four straight sides and four right angles, especially one with unequal adjacent sides, in contrast to a square.'
According to the given sum,
Width = w
Length = 2w - 19
Area of a rectangle = length × width
= w × (2w - 19)
= 2w ( squared ) - 19w
Hence, we can conclude that the expression that represents the area of the classroom floor is 2w (squared) - 19w.

Answer:
B
Step-by-step explanation:
The area is calculated by length×width. In this case you don't know the length or width precisely so you say 2w (squared) because it's the width×width and you subtract 19 because then you actually have width×length.
