Simplify the following:
x^3 - 2 x^3 + x - 3 x - 5 - 4
Grouping like terms, x^3 - 2 x^3 + x - 3 x - 5 - 4 = (-2 x^3 + x^3) + (x - 3 x) + (-5 - 4):
(-2 x^3 + x^3) + (x - 3 x) + (-5 - 4)
x^3 - 2 x^3 = -x^3:
-x^3 + (x - 3 x) + (-5 - 4)
x - 3 x = -2 x:
-x^3 + -2 x + (-5 - 4)
-5 - 4 = -9:
-x^3 - 2 x + -9
Factor -1 out of -x^3 - 2 x - 9:
Answer: -(x^3 + 2 x + 9)

Answer:
1)3/4
2)3
3)12 MILES
4)2.5 pounds
5)5/8 pounds
am not sure but hopefully it helps you!!!!!!
By definition, the slope is the inclination of a line in relation to the horizontal. It can be expressed in degrees, ratios and even in percent. Therefore, you can calculate it by applying the following formula:
P%=(H/L)x100
P% is the slope expressed in percent.
H is the height (H=1.2 meters).
L is the length (L=4 meters).
When you substitute these values into the formula P%=(H/L)x100, you obtain the slope of the skateboard ramp:
P%=(H/L)x100
P%=(1.2 meter/4 meters)x100
P%=0.30x100
P%=30%
4a5+28+6b7-30
4a5+6b7-2<—- this is a to the power of 5 , b to the power of 7
(Is that 5a or a to the power of 5 )
20a+28+42b-30
20a+42b-2<—— this is 5a , 7b
