Answer: b
Step-by-step explanation:
anser is b
x + 2x + 6 = 27
3x + 6 = 27
x + 2 = 9
x = 9 - 2
x = 7
2 × 7 = 14
14 + 6 = 20
Answer:
12$
this is a helper
P = 1000
r = 4.5% = 0.045
n = semi annually = 2
t = 4
in a 45-45-90 triangle, the sides are the same
you can find the third side using the pythagoran therum
but a and b are the same thing, so
if x is the side
so, like in problem 1
always make sure the hypotnus is longer than the legs
