Step-by-step explanation:
Volume of a prism:
Area of cross section x height
Answer:
j=46
Step-by-step explanation:
34=j-12
add 12 to 34 to isolate j
the answer to that is 46
j=46
Answer:
42
Step-by-step explanation:
x/3+12 = 26
Multiply everything by 3 to eliminate the fraction
x+36=78
subtract 36 on both sides
x=42
42/3=14
14+12=26
Answer:
x=9
Step-by-step explanation:
Use the intersecting chord theorem:
RE*ET = UE*ES
Substitute values
21 (2x+2) = 30 (x+5)
Expand:
42x+42 = 30x + 150
transpose and simplify
42x-30x = 150 - 42
12x = 108
x = 9
<span>length = L
</span>width = w
L = (5w-2) cm
width = 2 cm
length = 5w-2 = 5*2-2 = 8 cm
