Answer:
a) 10(3x+2) ≤ 140; x ≤ 4
b) no
Step-by-step explanation:
a) The area is the product of length and width. We want that product to be no greater than 140:
10(3x +2) ≤ 140 . . . . your inequality
We can solve this by dividing by 10 first.
3x +2 ≤ 14
3x ≤ 12 . . . . . . subtract 2
x ≤ 4 . . . . . . . . divide by 3; the solution to the inequality
__
b) If the length were 15, the area would be 10×15 = 150, which is greater than 140. The length cannot be 15 if the area is at most 140.
The perimeter is all the sides added up.
s1+s2+s3+s4= p
So, 12+ 6+ 8+ 17= the perimeter.
12+6+8+17 = 43
The answer is 43.
I hope this helps!

Answer:
120 y2
Step-by-step explanation:
The floor consists of a square and a triangle
area of square = 10² = 100 yd²
area of triangle = bh ( b is the base and h the height )
Here b = 4 and h = 10 , then
area = × 4 × 10 = 2 × 10 = 20 yd²
company needs 100 + 20 = 120 yd²
