Answer:
The missing side is 18 inches
Step-by-step explanation:
Since in the smaller rectangle the sides are 2.5in x 6in and one side for the larger rectangle is given, you can make an equation.

Then you can cross multiply.
2.5x=45
Divide by 2.5 on both sides.
x= 18
Answer:
9x^4 -x
Step-by-step explanation:
( -8x + 3x^4 ) - ( -7x - 6x^4 )
Distribute the minus sign
( -8x + 3x^4 ) +7x + 6x^4
Combine like terms
3x^4 + 6x^4 -8x +7x
9x^4 -x
Frist convert the mixed fraction to make it easier.
9/4
Then find the lowest common denominator (LCD) which in this case is 12 so multiply them both by fancy ones inorder for them to combine.
5/6 × 2/2 = 10/12
9/4 × 3/3 = 27/12
And now we can add them together.
10/12 + 27/12 = 37/12 = 3 and 1/12
