Given:
Side length of square = 2 in
To find:
The area of the square
Solution:
Area of the square:
Area = side × side
= 2 in × 2 in
Area = 4 in²
Therefore, the area of the square is 4 inches².
Xy = k
(-4/15)(-105) = k
28 = k
xy = 28
10y = 28
Divide both sides by 10
y = 2.8
Step-by-step explanation:
a=b+3
when b=3
a+b= b+3+b= 2b+3 = 6+3=9
