Step-by-step explanation:To add the three distances first align the decimal points, adding in place holder zeros if necessary. Then add each place value and rename when necessary.
7 mm x 9mm x 12mm = 756mm
To get this answer you have to multiply 9 and 12 which would be 108. Then you have to divide 108 on both sides to get mm by itself. 756 divided by 108 is 7 which is the answer!
I got -9z-273
Multiply -12 by 7z (-84z) and by 4 (48) and multiply 15 by 5z (75z) and -15 (-225) then combine like terms, Underlined combines with underlined : bold combines with bold <em>-84z</em><u>-48</u><em>+75z</em><u>-225</u>
