X = 8
4 * 8 = 32
32+0.5 = 32.5
Answer:
D should be the anwser if im not mistaken!
Step-by-step explanation:
rp= 6 cm and as u can tell the side where q,s lies is a little bit longer so itll be 1 cm longer the r,p!!
Answer:
Except -1(12w-6)
Step-by-step explanation:
It's equivalent to -12w+6 when expand
$1.75 by 5 is equal to $8.75. And if you were to do by 6 it would be 50 cents over. So Max can only buy 5 caramel apples.

3. 81
EXPLANATION
1. The given quadratic equation is
![{x}^{2} + 1 = 0](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20%2B%201%20%3D%200)
This implies that:
![{x}^{2} = - 1](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20%3D%20%20-%201)
There is no real number whose square is negative one.
This quadratic equation has no solution.
2. The given quadratic equation is
![{x}^{2} - 10x + 24 = 0](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20-%2010x%20%2B%2024%20%3D%200)
We split the middle term with -6,-4 because their product is 24 and their sum is -10
![{x}^{2} - 6x - 4x+ 24 = 0](https://tex.z-dn.net/?f=%7Bx%7D%5E%7B2%7D%20%20-%206x%20%20-%204x%2B%2024%20%3D%200)
We factor by grouping
![{x}(x - 6)- 4(x - 6)= 0](https://tex.z-dn.net/?f=%7Bx%7D%28x%20%20-%206%29-%204%28x%20-%206%29%3D%200)
![(x - 6)(x - 4)= 0](https://tex.z-dn.net/?f=%28x%20%20-%206%29%28x%20-%204%29%3D%200)
We have x=4 and x=6.
3. The given quadratic equation is
![{x}^{2} - 18x = 7](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20-%2018x%20%3D%207)
We the square of half the coefficient of x to both sides of the equation.
![( - \frac{18}{2} )^{2} = ( { - 9)}^{2} = 81](https://tex.z-dn.net/?f=%28%20%20-%20%20%5Cfrac%7B18%7D%7B2%7D%20%29%5E%7B2%7D%20%20%3D%20%28%20%7B%20-%209%29%7D%5E%7B2%7D%20%20%3D%2081)
The correct choice is C.
