Answer:
n=13/7
Step-by-step explanation:
2n+4+6*2=-9*2+8(2n+1)
2n+4+12=-18+16n+8
16+18=16n-2n+8
34=14n+8
34-8=14n
26=14n
n=13/7
Answer:
Well since we don't know what X or Y is, then we can't answer this question.
Step-by-step explanation:
7 = 2n - 2
n= a number so twice a number is 2n and 7 is 2 less than twice this number.
Answer:
-42
Explanation:
(-6)(-7)(-1)
do (-6)(-7)
-negative sign and -negative sign= +positive sign
(-6)(-7)=42
(42)(-1)
+positive sign and -negative sign=-negative sign
answer:
-42
The large triangle is an isosceles since both angles at the base each equal 42°.
In an isosceles triangle the altitude z is at the same time median , then it bisects the opposite side in the middle . So w = 120/2 = 60
Now let's calculate z:
tan 42° = (opposite side) / (adjacent side) = z/60
tan 42° = 0.9,
0.9 = z/60 and z = 54
