Answer:
15y^2 - 21y
Step-by-step explanation:
A = LW
A = (5y - 7)(3y)
A = 15y^2 - 21y
you can plug the x value (9y) into the second equation
5(9y) + 3y = -48
45y + 3y = -48
48y = -48
y = -1
x = 9(-1)
x = -9
Half of 23 would 11.5 and you had to do was divide 23 by 2
For this case we have the following expression:
3sqrt (8) / 4sqrt (6)
Rewriting we have:
3sqrt (2 * 4) / 4sqrt (6)
3 * 2sqrt (2) / 4sqrt (6)
6sqrt (2) / 4sqrt (6)
3sqrt (2) / 2sqrt (6)
3sqrt (2) / (2sqrt (2) sqrt (3))
3 / (2sqrt (3))
3sqrt (3) / (3 * 2)
sqrt (3) / (2)
Answer:
the following quotient is:
D.sqrt 3/2
