The right ans is D.I am 100%sure.
if my ans was gelpful u can follow me.
Answer:
length = 5
width = 9
Step-by-step explanation:
V = lwh
let 'x' = length
let '4+x' = width
9 = height
405 = 9x(4+x)
405 = 36x + 9x²
this is a quadratic equation: 9x² + 36x - 405 = 0
factor out a 9 to get:
9(x² + 4x - 45) = 0
9(x-5)(x+9) = 0
one root is 5 and the other is -9
since distance cannot be negative we use 5 as the length and 9 is the width
The total number of yards is 360 yards
<h3>How to determine the number of yards?</h3>
The given parameters are:
Number of sheets = 8
Yard per sheet = 45 yards
The total number of yards is calculated as:
Total number of yards = Number of sheets * Yard per sheet
Substitute the known values in the above equation
Total number of yards = 8 * 45 yards
Evaluate the product
Total number of yards = 360 yards
Hence, the total number of yards is 360 yards

Answer:
Step-by-step explanation:
Answer:
x > 2
Step-by-step explanation:
y < 4x +3
y > -2x - 9
-2x -9 < 4x +3
-6x < -12
IN CASES WHERE YOU DIVIDE A NEGATIVE NUMBER,DON'T FORGET TO CHANGE THE SIGN !!!
x > 2
