Answer:
8cm
Step-by-step explanation:
1. x = width
length = 2x - 4
(2x - 4)x = 96
2x ^ 2 - 4x - 96 = 0
x ^ 2 - 2x - 48 = 0
(x + 6)(x - 8) = 0
Since the width cannot be negative, the width would be 8cm.
Answer:
x = 136
Step-by-step explanation:
x and 44 are same- side interior angles and sum to 180° , that is
x + 44 = 180 ( subtract 44 from both sides )
x = 136

Answer:
7
Step-by-step explanation:
a right angle is 90 degrees so
90=76+2x subtract 76 from both sides
-76 -76
________
14=2x divide 2 from both sides
_ ___
2 2
7=x
Check:
76+(2*7)=90 correct
Answer:The volume of the reservoirs in in^3 is:
V = 30*14*(3/2)*12* (since 1 ft = 12 in)
1 gal = 231 in^3
((7/8)V) : 231 = ((7/8)30*14*(3/2)*12)/231 = 28.64 gal
28.64 gallons of oil are required to fill the reservoir to 7/8 of its depth.
