Answer:
I believe the answer is 26.I got it because you start of doing 13 times 4 which gives you 52 then you divide it by 2 or multiply by a half (1/2) and you get 26.
The best and most correct answer among the choices provided by your question is the second choice or letter B "20".
The current area is 120(80)=9600 and he want to expand it by 4400 so that the new area will be 9600+4400=14000
14000=(120+x)(80+x)
14000=9600+200x+x^2
x^2+200x-4400=0
x^2-20x+220x-4400=0
x(x-20)+220(x-20)=0
(x+220)(x-20)=0, since x is an increase it must be greater than zero so
x=20ft
(120+20)(80+20)=14000ft^2
I hope my answer has come to your help. Thank you for posting your question here in Brainly.
no because mathematically 30X10=300 not 900 its would have to be 30X30 to get the product of 900 so therefore no your statement is incorrect

Answer:
$80
Step-by-step explanation:
let x be the original price. the discount was 25%, so $60 is 75% of the original cost. we can set up this formula:
