(2w+4) (w) (18-w) = 1152
(2w^2+4w) (18-w) = 1152
Distributive property:
36w^2 -2w^3+72w-4w^2 =1152
Remember to use FOIL method:
-2w^3 +32w^2+72w-1152 =0
Like terms:
-2(w^3-16w^2-36w+576) = 0
Factor it by 2:
w^3 -16w^2-36w+576 =0
Simplify:
w^2(w-16)-36(w-16) =0
(w^2-36) (w-16) = 0
w= -6,6,16
Width:
w = 6,16
Since width is 16, then the height should be less than the width (18-16=2)

A car and a truck left Washington, DC traveling in opposite directions. The car
traveled 19 miles
per hour faster than the truck, and at the end of 8 hours they were
1048 miles apart. What was the average speed of each vehicle?
Answers
Answer:
The speed of the car is 75 mph.
The speed of the truck is 56 mph.
Step-by-step explanation:
Call the speed of the truck (x) miles per hour. As per the given information, the car is (19) miles per hour faster. Thus, one can form expressions to represent the speeds of the vehicles.
car = ( x + 19 ) mph
truck = ( x ) mph
Using the formula, ( (speed) * (time) = (distance) ), one can say that the speed of the car, times the time it took plus the speed of the truck times the time will equal the distance between the two vehicles:
(( car speed )( time )) + (( truck speed )( time )) = ( distance between vehicles )
Substitute,
( ( x + 19 ) ( 8 ) ) + ( ( x ) ( 8 ) ) = 1048
Simplify,
8x + 152 + 8x = 1048
16x + 152 = 1048
-152 -152
16x = 896
/16 /16
x = 56
Add (19) to find the speed of the car:
truck speed + 19
= 56 + 19
= 75
The speed of the car is 75 mph.
The speed of the truck is 56 mph.
Answer:
The truck traveled at 81
mph. The car traveled at 100
mph.

Takashi Caldwell has health insurance that pays 80 percent of coverage charges after a $150 deductible. She received a statement for $350 of covered charges. How much will Takashi have to pay?
Answers
Subtract the deductible from the total:
350 - 150 = 200
Takashi then needs to pay 20% of what is left.
200 x 0.20 = 40
Takashi has to pay the 150 deductible plus 40 for a total of $190

A prop for the theater club's play is constructed as a cone topped with a half-sphere. What is the volume of
the prop? Round your answer to the nearest tenth of a cubic inch. Use 3.14 to approximate pi. Complete
sentences
Answers
Answer:
Volume of the prop = 706.5 in³
Step-by-step explanation:
Volume of the prop given in the picture = Volume of hemisphere + Volume of the cone
Volume of the hemisphere = [tex]\frac{2}{3}\pi r^{3}[/tex]
where 'r' = radius of the hemisphere
For r = 5 in,
Volume of the hemisphere = [tex]\frac{2}{3}(3.14)(5)^{3}[/tex]
= 261.67 in³
Volume of a cone = [tex]\frac{1}{3}\pi r^{2}h[/tex]
Here r = radius of the circular base
h = height of the cone
For 'r' = 5 in and h 17 in.
Volume of the cone = [tex]\frac{1}{3}(3.14)(5)^2(17)[/tex]
= 444.83 in³
Volume of the prop = 261.67 + 444.83
= 706.5 in³

What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
The expression is,
⇒ 76/81 x 80/76
Now, We can solve as;
⇒ 76/81 x 80/76
⇒ (76 × 80) / (81 × 76)
⇒ 80 / 81
Thus, The solution of the expression is,
⇒ 80 / 81

Suppose two rectangles are similar with a scale factor of 2. What is the ratio of thier areas? Explain.
Answers
Answer:
4
Step-by-step explanation:
From the question,
Since both rectangle has a scale factor of 2,
L₁/L₂ = 2
Where L₁ and L₂ are the length of the first and second rectangle respectively
L₁ = 2L₂................ Equation 1
Also,
W₁/W₂ = 2............ Equation 2
Where W₁ and W₂ are the Width of the first and second rectangle respectively
W₁ = 2W₂
Area of a rectangle = Length × width
Area of first rectangle = L₁×W₁ = 2L₂×2W₂ = 4L₂W₂
Area of second rectangle = L₂×W₂= L₂W₂
The ratio of area = Area of the first rectangle/Area of the second rectangle = 4L₂W₂/L₂W₂ = 4

Pamela's parakeet is currently in a rectangular bird cage that has a length of 3 feet, a width of 2 feet, and a height of 3 feet. Since the parakeet has gotten larger, Pamela is looking to buy a new rectangular bird cage. She wants the new cage to have a volume that is 4 times the volume of the parakeet's current cage. If Pamela wants to keep the length of the new cage the same, how must the other dimensions change?
Answers
Answer:
The volume of existing cage = length x widht x height = 3 x 2 x 3 = 18 cubic ft
Now she wants cage with volume four times of this cage
New Volume = V1 = 18 x 4 = 72 cubic ft
Keeping length same = 3 ft
Length x width x height = V1
3 x Width x height = 72
Width x height = 72 /3
Width x height = 24
Now multiple of 24 must be the width and height.
Taking width = 6 ft and height = 4 ft, we will get our answer
Proof:
Length x width x height = V1
3 x 6 x 4 = 72
