(2x^3+9x)-(4x^2-15x+7)
(8x+9x)-(16x-15x+7)
(17x)-(1x+7)
16x+7
Answer:
8 < x < 2 has no solution because there is no number greater than 8 (8 < x), yet less than 2 (x < 2). It's impossible, so there is no solution.
If the inequality was something like 8 < x < 10, then it will work because 8 can be less than x and x can be less than 10.
Hope this helps and have a great rest of your day! :)
Answer:
d. Distributive property
Step-by-step explanation:
The <em>Distributive property</em> of multiplication over addition is what allows you to multiply each of the terms in parentheses by the factor outside parentheses. It tells you ...
a(b +c) = ab + ac
It works both ways, also allowing you to remove a common factor to outside parentheses.
To find the area of a trapezoid, we use the following formula:

In this formula a represents the area and b1 and b2 each represent a base of the trapezoid.
So, we have got the following information



Filling in the formula gives us:



Finally we have to divide both sides by 15.

Therefore, the height of the trapezoid is 10 meters.
Perpendicular = opposite sign and reciprocal slope
Slope would be negative and reciprocal of 1/3, slope = -3
Plug into y = mx + b
y = -3x + b, plug in point
-4 = -3(-6) + b, b = -22
Solution: y = -3x - 22
