Therefore, the width is 5x^2 + 4x - 6
She has 6 on Wednesday
Since we know that she has 4/9 left, 4/9 of 27 is 12. So she has 12 on Tuesday. Now 2/4 or 1/2 is left on Wednesday. Half of 12 is 6. So she has 6 left
Answer:
Step-by-step explanation:
x^2 - 6x - 40 = 0.....get the -40 to the other side
x^2 - 6x = 40....now take half of ur x term (6)....so its 3...then square it (3^2 = 9)...now add 9 to both sides
x^2 - 6x + 9 = 40 + 9
(x - 3)(x - 3) = 49
(x - 3)^2 = 49...take sqrt of both sides, eliminating the ^2
x - 3 = sqrt 49
x = 3 (+ - ) 7
x = 3 + 7 = 10 or x = 3 - 7 = -4
so x = 10 or x = -4
Answer:
135ml
Step-by-step explanation:
glass originally 4/12 full
it then became 9/12 full
therefore 75ml = 5/12
75/5= 15ml per 1/12
15x9= 135ml total
