Hoover dam, in the united states, is 233 meters high. ertan dam, in china, is 240 meters high. write and evaluate a numerical expression to find the difference between the heights of the two dams.

Numerical expression for the difference in their heights

The difference in their heights= 7 meters

Step-by-step explanation:

Given: The height of the Hoover Dam, in the United States = 233 meters

The height of Ertan Dam, in China = 240 meters

let h be the difference in their heights

The difference between the heights of the two dams is given by the numerical expression

Therefore, the difference the heights of the two dams is 7 meters.

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8
