3 ft = 1 yd.....so 10 ft = 10/3 = 3 1/3 yds

A = L * W
A = 4 * 3 1/3
A = 4 * 10/3
A = 40/3
A = 13 1/3 yds^2 <==

Use the substitution method to solve this system.<br> y = 2x+4<br> 3x+y = 9

dexar [7]

Answer:

x = 1; y=6

Step-by-step explanation:

y = 2x +4

3x + y = 9

Substitute 2x+4 for y in 3x+y = 9

3x + y = 9

3x + 2x+4 = 9

5x + 4 = 9

5x = 9-4

5x = 5

5x/5 = 5/5

x = 1

Substitute 1 for x in y = 2x +4

2(1) + 4

2 + 4

= 6

Answer:

6) b(3a^4-5c³)

7) 3x³yz(2x+5y)

8) 4a²b²c³(2bc-3a)

9) 4xy(2y+7z-1)

10) 2mn(5n²+2m-3n)

Step-by-step explanation:

6) Factor out the b and you get b(3a^4-5c³)

7) Factor out the 3x³yz and you get 3x³yz(2x+5y)

8) Factor out the 4a²b³c³ and you get 4a²b²c³(2bc-3a)

9) Factor out the 4xy and you get 4xy(2y+7z-1)

10) Factor out the 2mn and you get 2mn(5n²+2m-3n)

PLEASE HELPPP

lianna [129]

Answer:

56.52 cm

Step-by-step explanation:

To find the circumfrence use this formula-> C=2πr

The Radius is 9 (and I'm assuming to use 3.14 for pi since it doesn't state whether to use 22/7 or 3.14)

$C= 2$\cdot$ 3.14 $\cdot$ 9$

C= 56.52 cm
