Answer:
Step-by-step explanation:
<u>Is this equation written correctly?:</u>
<u></u>
v(x)=12-2x-5.8
v(x) = -2x+6.2
v(-2) = -2(-2)+6.2
<u>v(-2) = 2.3</u>
v(0) = -2(0)+6.2
<u>v(0) = 6.2</u>
v(-5) = -2(-5)+6.2
v(-5) = 10+6.2
v(-5) = 16.2
explain this a little bit better im pretty sure you decrease 25 by 1/5th
The height of the rectangular pyramid is 7 ft.
<h3>
How to get the height of the rectangular pyramid?</h3>
First, we know that the volume of a rectangular pyramid is given by:
Where B is the base, H is the height.
First, we know that the volume is 56 ft³, and the base is 24ft², then we can replace these two in the volume equation to get:
Solving that for H, we get:
The height of the rectangular pyramid is 7 ft.

Answer:
x=20
Step-by-step explanation:
Well we know the right angle is 90 so...
And we also know that all the angle of a triangle add up to 180°.
Knowing this you can subtract 40° and 90°, this gives you 50°...
Then you can substitute 20° for x and then it will be 2(20°)+10°
Simplify and get 40°+10°
This equals 50° degrees
You then add that all up and you get 180°, this mean the answer is correct!
Hope this helps!

(2x2 + x − 3 )(x − 1.)
= 4x3 + x2 - 3x - 2x2 - x + 3
= 4x3 - x2 - 4x + 3
