A(1) = 6 = d + c
<span>a(4) = 33 = 4d + c </span>
<span>3d = 27=> d=9 </span>
<span>c = -3 </span>
<span>a(2) = 9(2) - 3 = 15 </span>
<span>a(3) = 15 + 9 = 24</span>
Answer:
2
Step-by-step explanation:
divide both sides by 4, so that y is alone
Answer:
396 ft³
Step-by-step explanation:
V = height × base × length
Since this is a prism, we divide it by 2.
V = (8ft × 9ft × 11ft) ÷ 2
= 396 ft³
Answer:
x=40
Step-by-step explanation:
Area of a triangle = B*H/2
First, you have to find the relationship between the large triangle and the smaller triangle. 72 is three times as much as 24, so to find x, you would have to find the relationship between 120 and x. So, 120/3 = 40.
Rational because you can write that as 39/1, and irrational numbers cannot be written as fractions.
