I believe I can fly, I believe I can’t touch the sky.
Answer:
84
Step-by-step explanation:
i swear
4 + 2(3x - 7) + 5x
Distribute
4 + 6x -14 + 5x
Combine like terms
-10 +11x or 11x - 10
Third option
Answer:
24. a. perimeter=6x-6 or 6(x-1) b. area=2x²+x-28
25. -5x² and 2x are not like terms so you cannot combine them.
Step-by-step explanation:
24. a. perimeter:
add up each side:
(2x-7)+(2x-7)+(x+4)+(x+4)= 6x-6 or 6(x-1)
b. area:
F.O.I.L.:
(2x-7)(x+4)=2x²+8x-7x-28
2x²+x-28
Answer:
x + 4y + z = 4
Step-by-step explanation:
The standard equation is of the form, Ax + By + Cz = 0
The equation of the plane that passes through the point(-1, 1/2, 3) and is perpendicular to [1, 4, 1] is
A = 1, B = 4, C = 1
x = -1; y = 1/2; z = 3
A(x-(-1)) + B(y-1/2) + C(z-3) = 0
(x+1) + 4(y-1/2) + (z-3) = 0
(x+1) + (4y-2) + (z-3) = 0
x + 1 + 4y -2 + z -3 = 0
x + 4y + z - 4 = 0
x + 4y + z = 4
