1.
(3x - 5 ) + (-4x + 1)
= 3x - 4x -5 + 1
= -x - 4
2.
6(-2.1k - 2) + (7k + 5)
= (-12.6k - 12) + (7k + 5)
= -12.6k + 7k - 12 + 5
= -5.6k - 7
3.
(2m + 7) - (3 - 4m)
= 2m + 7 - 3 + 4m
= 6m + 4
Answer:
10√2
Step-by-step explanation:
5√2³ = 5√8 = 5√(2 x 4) = (2 x 5)√2 = 10√2
256.
The coefficient of just the y term would be 256 because the entire expanded equation looks like this:
y^4+16y^3+96y^2+256y+256
So the equation for a trapezoid is

, with the b variable being the 2 bases, h variable for height, and the a variable for area. Firstly, we will need to plug in the appropriate numbers into the equation, and it'll look like this:

Next, we will need to combine 12 and 14, then divide the sum by 2. Your equation should look like this:

Lastly, just divide each side by 13, and your answer should be
