I think it’s 74 bc I got it right but your might be different
Step-by-step explanation:
length of a rectangle = (3x+4)
breadth of a rectangle =(2x-1)
perimeter of a rectangle =?
we know that,
perimeter of a rectangle=2 (length+breadth)
2 (3x+4)+(2x-1)
(6x+8)+(4x-4)
(6x+4x)+(4+8)
10x+12
x=12-10=2
x=2#
Answer:
-5x^2-32x+13
Step-by-step explanation:
(3-13x-7x)-(5x^2+12x-10)
3-20x-5x^2-12x+10
-5x^2-32x+13
