32+2/3(21y-6) in factored form

Mathematics
1 answer:
artcher [175]3 years ago
6 0

Answer:

14(y + 2).

Step-by-step explanation:

32 +2/3(21y - 6)

Distributing the 2/3 over the parentheses:

= 32 + 2/3*21y  + 2/3 * -6

= 32 + 14y - 4

= 14y + 28

= 14(y + 2).

What is the value of x in this proportion?
schepotkina [342]

Answer:

  (a)  -20 1/2

Step-by-step explanation:

The proportion can be solved using "cross multiply" as the first step. This eliminates the fractions and turns it into a linear equation.

  2/7 = -5/(x +3) . . . . . given

  2(x +3) = -35 . . . . . . multiply by 7(x +3)

  2x = -41 . . . . . . . . . simplify, subtract 6

  x = -20 1/2 . . . . . . divide by 2

6. Sketch the region enclosed by the graphs of x =0, 6y-5x=0 and x+3y=21. Find the area
Lyrx [107]
X = 0

<span>6y - 5x = 0 so it intersects x=0 at (0,0)
</span>
<span>x + 3y = 21
</span>so it intersect x=0 at (0,7)
multiply by 2
<span>2x + 6y = 42
subtracting 6y - 5x = 0
7x = 42
x = 6
so the third line intersects w second line at (6,5)

6. area of triangle = 1/2*base*height
= 1/2*7*6
=21

7. volume = volume of 2 cones
cone volume = 1/3*pi*radius^2*height
lower cone: radius=6, height=5
upper cone: radius=6, height=7-5=2
volume = 1/3*pi*6^2*(5+2)
=84pi
=263.89
