Estimation- 16 plus 13 plus 9 plus 10 plus 18= 66 ounces
Exact- 65.43 ounces
X= width
length= 3x-7
Area: (x)(3x-7)=40
= 3x^2-7x=40
= 3x^2-7x-40=0
Factorise the equation: (3x+8)(x-5)=0
x=-8/3 (reject because width cannot be negative) or x=5
so width is 5cm and length is 3(5)-7= 8cm !
Answer:
x = 12
Step-by-step explanation:
39/26 = 1.5
18/x = 1.5
18 = 1.5x
18/1.5 = x
12 = x
