To solve the exercirses which are shown in the figure attached, you must follow the proccedure below:
7) (x)=x³-6x²+8x
(x)=x(x³-6x²+8)
(x)=(x-4)(x-2)x
The lenght is: x
The height is= (x-4)
8) √(2x+8)-6=4
1. You need to clear the variable "x". Then:
√(2x+8)=4+6
√(2x+8)=10
(√2x+8)²=10²
2x+8=100
2x=100-8
x=92/2
x=46
9) l4x+3l=9+2x
1. To solve the left member, you must evaluate two cases: it could be positive,or negative. Then:
2. Negative:
l4x+3l=9+2x
-4x-3=9+2x
-4x-2x=9+3
-6x=12
x=12/-6
x=-2
3. Positive:
l4x+3l=9+2x
4x+3=9+2x
4x-2x=9-3
2x=6
x=6/2
x=3
Answer:
y = -4
Step-by-step explanation:
12y + 4 = 8y-12
Subtract 8y from each side
12y - 8y +4 = -12
4y +4 = -12
Subtract 4 from each side
4y +4-4 = -12 -4
4y = -16
Divide by 4
4y/4 = -16/4
y = -4

L= 78 si P=256
P=2L+2W w e width(latime)
256=2*78+2w
256=156+2w
256-156=2 w
100=2w
w=50
Answer:
6.3 units (nearest tenth)
Step-by-step explanation:
Using the formula above,
distance between (-8, 6) and (-6, 0)
![= \sqrt{ {[ - 8 - ( - 6)]}^{2} + {(6 - 0)}^{2} }](https://tex.z-dn.net/?f=%20%3D%20%20%5Csqrt%7B%20%7B%5B%20-%208%20-%20%28%20-%206%29%5D%7D%5E%7B2%7D%20%20%2B%20%20%7B%286%20-%200%29%7D%5E%7B2%7D%20%7D%20)
= 6.3 units (nearest tenth)
