Ответ:
area = 8x^2 - 2x - 15
Step-by-step explanation:
area = length x width
area = (2x-3) x (4x+5)
area = 8x^2 + 10x - 12x - 15
reduce:
area = 8x^2 - 2x - 15
Ответ:
Area is determined by using the formula A=lw Area= Length x Width
A= 1 1/4 x 3 convert to an improper fraction
A= 5/4 x 3/1 multiply
A=15/4 divide
A=3 3/4 square feet
