Answer:
25 sq ft
Step-by-step explanation:
I used a calculator.
You take 4x +9x and you get 13x then you take 13 +3 and you get 16 so you have the equation 13x+16=120. then you subtract 16 from both sides and you end up with 13x=104 then divide 104 by 13 and you get x=8
Answer:
the greatest common factor is 2
Step-by-step explanation:
none of the other numbers listed can go into 10, 14, and 16.
I substituted the ordered pairs into the equation.
(1,1)
1 = 3 * 1 - 4 The equation equals -1 for the y, this ordered pair does not
(y) (x) make this equation true.
(2,2)
2 = 3 * 2 - 4 This equation equals 2 for the y, this ordered pair makes this
(y) (x) equation true.
(3,6)
6 = 3 * 3 - 4 This equation equals 5 for the y, this ordered pair does not
(y) (x) make this equation true.
(4,9)
9 = 3 * 4 - 4 This equation equals 8 for the y, this ordered pair does not
(y) (x) make this equation true
So I would go with B. (2,2)
