138 x ? = 75
? = 75/138 = 0.544(3sf)
so about 54.35% (2dp) decrease
length is 8m
Width is 6.5m
<u>Explanation:</u>
Let, width = b
So, length = 2b-5
area = 52
We know,
area of rectangle = length X width
So,
= 
On solving the above equation, we get
Width, b = 6.5m
length, l = 8m
Answer: It's 36
Step-by-step explanation: add 5+4(equals 9) then multiply 9 by 6(whih equals 36

Answer:
≤ − 8
Step-by-step explanation:
-1 ≤
-3
4 ×(-1) ≤ 4 ×
-4×3
-4 × (-1) ≤ -x - 4×3
-4 ≤ -x - 12
x ≤ -12 + 4
x ≤ -8
Answer:
length=(3x-2)
Step-by-step explanation:
area of rectangle=length*breadth
3x^2 + 7x - 6=length * (x+3)
3x^2 +(9-2)x -6=length *(x+3)
3x^2+9x-2x-6=length*(x+3)
3x(x+3)-2(x+3)=length*(x+3)
(x+3)(3x-2)=length*(x+3)
(x+3)(3x-2)/(x+3)=length
(3x-2)=length
