Answer:
IM TERRIBLE IN GEOMETRY
Step-by-step explanation:
4, 12, and 18 in two different ways
<span>(4 + 12) + 18 = 16 + 18 = 34
4 + (12 + 18) = 4 + 30 = 34
answer is B) </span><span>(4 + 12) + 18 = 16 + 18 = 34; 4 + (12 + 18) = 4 + 30 = 34 (second choice)</span>
-2x + xy = 30.....when y = 8
-2x + 8x = 30
6x = 30
x = 30/6
x = 5 <==
Step-by-step explanation:
-8 - -4= -8+4=-4
16- -4=20
8- -4=12
-9--4=-5
