ANSWER THIS NOW please. An amusement park constructed a new ride called the "Haunted Hotel." There are x2 –
3 floors in this hotel. Each floor is 2x2 + 5 feet high. Which expression shows the total
height of this hotel?
Answer:
2x⁴ - x² - 15
Step-by-step explanation:
(X² - 3)(2x² + 5)
[x²(2x² + 5)] - [3(2x² + 5)]
= 2x⁴ - x² - 15
A certain television is advertised as a 10-inch TV (the diagonal length). If the width of
the TV is 6 inches, how many inches tall is the TV?
Answer:
8 in
Step-by-step explanation:
Given data
DIagonal= 10 in
Width= 6 in
`Height=???
We know that the expression that can be used to find the missing dimension is given as
d^2= w^2+h^2
substitute
10^2=6^2+h^2
100= 36+h^2
100-36= h^2
64= h^2
h= √64
h= 8 in
Hence the height is 8 in
A bag contains 3 red marbles. The ratio of red marbles to blue marbles is 3 : 7. Find the number of blue marbles in the bag.

If Matt earns eight dollars per hour and h is the number of hours Matt works, which expression represents how much money Matt earns?
Answer:
8(h)=x
Step-by-step explanation:
Matt earns 8 dollars for every hour he works. So you multiply the total numbers worked (h) by 8. That will give you the amount of money he's made(x) so the equation would be 8(h)=x

36/2^5 over 8+7x(3+11)
Answer:
119.25
Step-by-step explanation:
36/32 simplified is 9/8.
8 + 7(3+11), I'm assuming it's not x.
8 + 7(14) = 106
(9/8)/106 = 9/8*106 = 954/8 = 119.25
Hope this helps, lmk if the "x" is actually a variable instead of multiplication :)

−2x=x2−6 Rewrite the equation by completing the square.
Answer:
(x + 1)² = 7
Step-by-step explanation:
Given:
-2x = x² - 6
We'll start by rearranging it to solve for zero:
x² + 2x - 6 = 0
The first term is already a perfect square so that's fine. Normally, if that term had a non-square coefficient, you would need to multiply all terms a value that would change that constant to a perfect square.
Because it's already square (1), we can simply move to the next step, separating the -6 into a value that can be doubled to give us the 2, the coefficient of the second term. That value will of course be 1, giving us:
x² + 2x + 1 - 1 - 6 = 0
Now can group our perfect square on the left and our constants on the right:
x² + 2x + 1 - 7= 0
x² + 2x + 1 = 7
(x + 1)² = 7
To check our answer, we can solve for x:
x + 1 = ± √7
x = -1 ± √7
x ≈ 1.65, -3.65
Let's try one of those in the original equation:
-2x = x² - 6
-2(1.65) = 1.65² - 6
- 3.3 = 2.72 - 6
-3.3 = -3.28
Good. Given our rounding that difference of 2/100 is acceptable, so the answer is correct.
pam is 17 years old and her sister is 9. her two brothers are 11 and 7 years old. what is the mean of their ages
Answer:
11
Step-by-step explanation:
17+9+11+7 divided by 4
because the mean= sum of the terms divided by the number of terms
the sum= 17+9+11+7=44
the number of terms= 4
44 divided by 4= 11
Answer:
(17+9+11+7) / 4 mean is an average
it is equal to the sum of the elements divided by the number of elements
the sum is 44
the number of elements is 4
the mean is the average= 44/4=11

An angle measures 27.2° less than the measure of its supplementary angle. What is the measure of each angle?
Answer:
Step-by-step explanation:
Supplementary angles have a sum of 180 degrees.
a+a-27.2=180
2a-27.2=180
2a=207.2
a=103.6, and since b=a-27.2
b=76.4
So one angle is 103.6 degrees and the other is 76.4 degrees.

Toni bought 5 t-shirts for 35 if each T-shirt cost the same amount .how much tony would pay for20 shirts 
Answer: The answer is Toni can buy 20 tee shirts for 140 dollars
Step-by-step explanation:
First you find out how many times 5 can go into 20
Next you see that 5 can go into 20, 4 times so you take the 35 and multiply 4 and you get 140 so you can buy 20 tee shirts for 140 dollars.

Help me, please! I need help with this.
Answer:
x = 9
Step-by-step explanation:
Because the angles are vertical angles their measures are congruent so make them equal to each other:
3x -8 = 2x +1 subtract 2x from both sides
-2x -2x
x -8 = 1 add 8 to both sides
+8 +8
x = 9

The length of a rectangle is (3x - 1) and its width is ( 2x + 5). What is the area of the rectangle?
Answer:
3x^2 + 13x - 5
Step-by-step explanation:
To find the area, you multiply the length by width. So its is (3x - 1) * (2x + 5)
Then distribute. (3x * 2x) + (3x *5) + (-1 *2x) + (-1 * 5)
So 3x^2 + 15x -2x -5
Final Answer: 3x^2 + 13x - 5
