I'm gonna hazard a guess at 309.
121+121=242
242-224=18
224-121=103
103-18=85
224+85=309
Answer:
x = -10
Step-by-step explanation:
-4x - 18= 22
-4x = 22 + 18
-4x = 40
x = 40/-4
x = -10
Answer:
Area =
square feet
Step-by-step explanation:
The area of a rectangle is given by the formula:
A = length * width
Where length is 91 feet and width is
feet
Before we do the multiplication, we have to change the mixed number [width] into an improper fraction by using the rule shown below:

Hence,

So, the area is:
Area =
square feet
Answer:
12xy
Step-by-step explanation:
For rectangle A, the length would be (x+3x) and the width would be 3y, so 4x*3y = 12xy
