61+69+45= 175 years added together
Step-by-step explanation:
Emily is 61
Colin is 61+8=69
and Dan is 61-16 which is 45, so when you add them together you get 175 years
Dimensions of the hallway mural:
L = x + 6, W = x - 2.
An expression is:
A ( hallway mural ) = ( x + 6 ) · ( x - 2 )
If x = 8 ft ( length of each side of the classroom ):
A ( h. m . ) = ( 8 + 6 ) · ( 8 - 2 ) =
= 14 · 6 = 84 ft²
The area of the hallway mural is 84 ft².
D.) 9,987,000 becomes 9.987 x 10^6
