Multiply the variable k times 4 would give you 4k.
Then cross multiply 14x8 = 112
Therefore, you would have 4k = 112.
Divide 112 by 4 to get your answer!
Answer:
The answer is 9x-4.
Step-by-step explanation:
First calculate the area of the backyard. This is 13x-1. Then multiply the area of the patio so multiply x +3 by x+ 3. The answer to this is 4x+3. Next subtract the area of the patio from the area of the backyard. The answer is 9x-4.
Answer:
Step-by-step explanation:
Let the length of rectangle A be x units.
So, length of rectangle B
= x + 25% of x
= x + 0.25x
= 1.25x
Let the width of rectangle A be y units
So, Width of rectangle B
Area of rectangle A = xy
Area of rectangle B
= 1.25x * 0.6y
= 0.75xy

Answer:
x=-5
Step-by-step explanation:
25 - 3x = 40
-3x + 25 =40
-3x +25--25=40-25
-3x=15
-3x÷-3=25÷-3
x=-5
