= 2ab + 4a + 6 - 6
= 2ab + 4a
you can factor this to 2a(b + 2)
42%7=6. 6 times 5 is 30. 30 cakes in 5 days.
I did it wrong the first time you're answer is b. 11*11^4
The area of rectangle is 15x - 25y + 30 sqaure units
<em><u>Solution:</u></em>
Given that, a rectangle with a length of 5 and a width of 3x - 5y + 6
To find: Area of rectangle
<em><u>The area of rectangle is given by formula:</u></em>

From given,
Length = 5
Width = 3x - 5y + 6
<em><u>Substituting the values in formula, we get,</u></em>

Thus area of rectangle is 15x - 25y + 30 sqaure units
