Answer:
3 lessons
Step-by-step explanation:
available hours: 4 hrs 30 min
time per lesson: 1 hr 30 min
2 lessons is 3 hrs
which leaves even time for one more lesson after 2 lessons
So, she can schedule 3 lessons in 4 hrs in 30 min
9x^3 y^5
Since the formula to finding area is (L*W = A), we first have to find the width.
Width: 3x^3 y^5 times 2 = 6x^3 y^5
Then we add them. So, 3x^3 y^5 + 6x^3 y^5 = 9x^3 y^5
'dz' because d and z are different values.
2
3 x 2 = 6
3^2 • 3^x=3^(2+x)
3^(2+x)=3^7
=> 2+x=7
x=5
