Answer:
D. 270 cm2
Step-by-step explanation:
2*(15*5 + 15*3 + 5*3) = 270 cm2
Answer :6x + 5y = 30
5y = 30 - 6x
y = 6 - (6/5) x
So slope = -6/5
Perpendicular line has slope 5/6 (product of the slopes is -1)
So y = 5/6 x + b
Passed through (-6, -7) so -7 = -5 + b
Sp b = -2
So y = (5/6)x - 2

9514 1404 393
Answer:
B -11 4/15
Step-by-step explanation:
-7 3/5 -3 2/3 = -(7 3/5 +3 2/3)
= -((7 +3) +(3/5 +2/3)) = -(10 +9/15 +10/15)*
= -(10 +19/15) = -(10 +1 4/15)
= -11 4/15
___
* you know at this point that the correct answer is B. The integer part cannot be 10, but must be 11.
