Bob has 27 books.
Charles has two thirds as many books as Bob.
![27 \times \frac{2}{3}=9 \times 2=18](https://tex.z-dn.net/?f=27%20%5Ctimes%20%5Cfrac%7B2%7D%7B3%7D%3D9%20%5Ctimes%202%3D18)
Charles has 18 books.
Jim has three times as many books as Charles.
![18 \times 3=54](https://tex.z-dn.net/?f=18%20%5Ctimes%203%3D54)
Jim has 54 comic books.
Answer:
Its the fourth x=-2w/v
X=- 8x=4 x=2+5i
(x+8)(x-4)(x-(2+sqrt(-25))
x^2+4x-32(x-2+sqrt(-25))
x^3+4x^2-32x-2x^2+8x-64+x^2(5i)+4x5i-32(5i)
now simplify
Answer:
B 3
Step-by-step explanation:
We can use the secant-secant formula:
(whole secant) x (external part) =
(whole secant) x (external part)
9 * 4 = 12 *x
36 = 12x
Divide each side by 12
36/12 =12x/12
3 =x
Answer:
l=14 yards and w=5 yards
Step-by-step explanation:
Let the width be w units, then the length of the rectangle is:
![l = 2w + 4](https://tex.z-dn.net/?f=l%20%3D%202w%20%2B%204)
The area of the rectangle is given as 79 square yards.
This implies that:
![w(2w + 4) = 70](https://tex.z-dn.net/?f=w%282w%20%2B%204%29%20%3D%2070)
Expand:
![2 {w}^{2} + 4w = 70](https://tex.z-dn.net/?f=2%20%7Bw%7D%5E%7B2%7D%20%20%2B%204w%20%3D%2070)
O
![{w}^{2} + 2w - 35 = 0](https://tex.z-dn.net/?f=%20%7Bw%7D%5E%7B2%7D%20%20%2B%202w%20-%2035%20%3D%200)
We factor to get:
![(w - 5)(w + 7) = 0](https://tex.z-dn.net/?f=%28w%20-%205%29%28w%20%2B%207%29%20%3D%200)
![w = 5 \: o r\: w = - 7](https://tex.z-dn.net/?f=w%20%3D%205%20%5C%3A%20o%20r%5C%3A%20w%20%3D%20%20-%207)
Since we are talking about length, we have width equal 5 yards.
The length is:
![l = 2 \times 5 + 4 = 14yds](https://tex.z-dn.net/?f=l%20%3D%202%20%5Ctimes%205%20%2B%204%20%3D%2014yds)
