add 8 1/2 + 2 1/2=11
add 11 + 2 1/2=13 1/2
the area would be 11 x 13 1/2
It’s reflected across the origin. Or to the right across the y axis. Then down across the x axis
Answer:
(13y + 15) -9y
-117y - 135
Step-by-step explanation:
Distribute -9y to the inside numbers in the parentheses -117y and -135 are not compatible to each other ( because the -135 doesn't have a y ) so that would give you your final answer of:
-117y -135
9514 1404 393
Answer:
(d) 8
Step-by-step explanation:
Corresponding sides are proportional.
ED/EG = EC/EF
(6x +3)/17 = (8x -1)/21
21(6x +3) = 17(8x -1)
126x +63 = 136x -17
80 = 10x . . . . . . . . . . . add 17-126x
8 = x . . . . . . . . . . divide by 10
