The answer is 39 and I know because I took the test and got it right
Answer:
length= 9
width= 3
Step-by-step explanation:
x= width
length = x+6
x+6+x+6+x+x=24
4x+12=24
take 12 from both sides
4x= 12
x=3
Answer:
a₅=27.
Step-by-step explanation:
1) according to the condition the given subsequence is arithmetic sequence. It means, the a₁=7 and d=5, then
2) a₅=a₁+4*d; => a₅=7+4*5=27.
Step-by-step explanation:
y = x - 4 and y = 4x + 2
=> x - 4 = 4x + 2
=> 3x = -6
=> x = -2
y = x - 4 = (-2) - 4 = -6
The solutions are x = -2 and y = -6.
x = 16 x sin(60) = 8sqrt(3)
answer is B.
