$9.24 is your answer, which means all you had to do was subtract $17.16 from $26.40 and you would get $9.24
Answer:
The answer is 0
Step-by-step explanation:
I took the test
Law of cosine:
c² = a² +b² -2ab*cosC.
Because the triangle is equilateral a=b=c=x,
and we can write,
x²=x² +x² -2xx*cosC
x² =2x² -2x²* cos C
-x² = -2x²*cos C
cos C= 1/2,
so m∠C=60⁰.
Because all sides are equal, and across of the equal sides should be equal angles, all angles will be also equal and = 60⁰.
<em>Answer:</em>
<em>B</em>
<em>Step-by-step explanation:</em>
<em>If h is hours, then we can substitute 2 into the equation.</em>
<em>K = 30(2) + 40</em>
<em>K = 60 + 40</em>
<em>K = 100</em>

Answer:
Step-by-step explanation:
1) if the given sequence is 9;5;1;-3, then a₁=9; a₂=5; a₃=1 and a₄=-3 and
2) the difference is -4.
3) if the difference is -4, then the correct answer is A: aₙ=aₙ₋₁ - 4.
