3 balls of wool because 4 balls of wool/8 caps=1/2 ball of wool to make each cap. 1/2 ball x 6 caps=3 balls of wool.
X +x²= 132
x +x²-132= 132-132
x²+x -132 = 0
(x-11) (x+12) = 0
x-11 = 0 X+12=0
x-11+11 = 0+11 X+12-12=0-12
x =11 x= -12
Check
x +x²= 132 x +x²= 132
-12 +-12²= 132 11 +11²= 132
-12 + 144 = 132 11+ 121=132
132= 132 132=132
Since the problem says positive the answer is (11,121)
Answer:
3 ft, 3ft, 5ft => 45 cubic feet
6 ft, 2 ft, 4 ft => 48 cubic feet
7 ft, 2 ft, 2 ft => 28 cubic feet
6 ft, 5 ft, 2 ft => 60 cubic feet
Step-by-step explanation:
Recall: formula for volume of a rectangular prism is given as, V = L × W × H
✔️Volume of rectangular prism with the following dimensions:
L = 3 ft
W = 3 ft
H = 5 ft
V = 3 × 3 × 5
V = 45 cubic feet
✔️Volume of rectangular prism with the following dimensions:
L = 6 ft
W = 2 ft
H = 4 ft
V = 6 × 2 × 4
V = 48 cubic feet
✔️Volume of rectangular prism with the following dimensions:
L = 7 ft
W = 2 ft
H = 2 ft
V = 7 × 2 × 2
V = 28 cubic feet
✔️Volume of rectangular prism with the following dimensions:
L = 6 ft
W = 5 ft
H = 2 ft
V = 6 × 5 × 2
V = 60 cubic feet
Answer:
6
Step-by-step explanation:
Given
3x - 15 ≥ 3 ( add 15 to both sides )
3x ≥ 18 ( divide both sides by 3 )
x ≥ 6
Since x is greater than or equal to 6 then 6 is a solution
Answer:
y=2x+6
Step-by-step explanation:
to write the equation you just need to plug in numbers
y=mx+b
the m is the slope and the b is the y intercept
