3 0

Answer:

\boxed{\text{3 in}}

Step-by-step explanation:

1 in = 190 ft

x in = 570 ft

We can use ratio and proportion to solve this problem.

\begin{array}{cccl}\dfrac{1}{x} & = & \dfrac{190}{570} & \\\\570 & = & 190x & \text{Mutiplied by lowest common denominator (570x)}\\3 & = & x & \text{Divided each side by 3}\\\end{array}

The building will be \boxed{\textbf{3 in}} tall in the scale drawing.

For the polynomial –2m2n3 + 2m?n3 + 7n2 – 6m4 to be a binomial with a degree of 4 after it has been fully simplified, which must
andrew-mc [135]

Answer:

(C)2

Step-by-step explanation:

Given the polynomial:

-2m^2n^3 + 2m^{\boxed{x}}n^3 + 7n^2 - 6m^4

where x is the missing exponent.

We desire our polynomial to be a binomial (have two terms) after simplification.

We observe that the first and second term are positive and negative of almost the same term.

Therefore, we rewrite the polynomial in such a way that the first and second term cancels out.

This is:

-2m^2n^3 + 2m^{\boxed{2}}n^3 + 7n^2 - 6m^4\\$Simplified, we have:\\\\=7n^2 - 6m^4

Therefore, the missing exponent on the m in the second term is 2.
