<span>So, L*W=A Because it is 4 cm longer, L=W+4 Because the area is 96, LW=96 Substitute to get W(W+4)=96 Multiply it out. W^2+4W-96=0 By solving the quadratic, W+12(W-8)=0 so either W+12 or W-8 is zero. The width must be positive, so the width is 8. Therefore the length is 12.
Hope this helps.</span>
Answer:
about 8 classes
Step-by-step explanation:
convert 6 3/4 to a fraction: 27/4
3/4 can go into 27/4 9 times, but with time in between, you should only be able to have 8 classes instead of 9
Answer:
Step-by-step explanation:
First, subtract 3 from x
This will get you the expression x - 3
Now, divide this by 6.
This will get you the expression
So, the final expression from the steps is
Answer:
x = 20/33
Step-by-step explanation:
-6.6x = -4
Divide both sides by -6.6.
x = -4/(-6.6)
x = 40/66
x = 20/33
Substitute the values of a and b into the expression:
11 + 3 - 2
Add first because of order of operations (perform addition and subtraction in the order of occurrence from left to right):
14 - 2
Subtract (same justification as above just with subtraction instead):
12
Hope this helps!
