Step-by-step explanation:
Answer:
A.−3x^4+2x^2−4x
B.4p^7−10p^5+2p^4
Step-by-step explanation:
A.x(−3x^3+2x−4) then simplify −3x^4+2x^2−4x
B. -2p^3(-2p^4+5p^2-p) then simplify 4p^7−10p^5+2p^4
Answer:
80n+20=total cost
Step-by-step explanation:
We don't know the value of n, but we don't need it for an expression. We know that the family has to pay $80 per night that they stay at the hotel. Modeling this would look like: 80n (80*n for nights). Also, we know that the family MUST pay a $20 fee. So, we can add that on to the expression to look like this, 80n+20=total cost.
Hope this helps!
Have a nice evening.

What does T(110) means
First, we calculate T(110):
Substitute 110 for w in
The expression becomes
<em> -- approximated</em>
<em>T(100) represents that the plane flies against the wind at 110mph for 0.714 hours</em>
Answer: True
One angle of a right triangle = 90°
Let x = the acute angle of one angle.
Let y = the angle of the other angle.
Because the sum of angles in a triangle is 180°,
x + y + 90 = 180
x + y = 90
y = 90 - x
Therefore the angles for each of the two triangles are
x, 90° - x, 90°.
The two triangles are therefore similar because of AAA (Angle, Angle, Angle).
