Answer:

1. 1,016 sq. m.

2. 119 sq. m.

Step-by-step explanation:

14 x 18 = 252

18 x 8 = 144

14 x 8 = 112

2 ( 252 ) + 2 ( 144 ) + 2 ( 112 )

504 + 288 + 224 = 1,016 sq m

4 (7 x 5 divided by 2) + (7 x 7) =

7 x 5= 35 divided by 2 = 17.5 x 4 = 70 + 49 = 119 sq. m.

I hope this helps

sorry if i'm wrong

In the equation (x^2+y)^5, what is the coefficient of the term x^4y^3? what is the coefficient of the same term in the expansion

lys-0071 [83]

$\displaystyle
(x+y)^n=\sum_{k=0}^n\binom{n}{k}x^{n-k}y^k$

-------------------------------------------------------------

$\displaystyle
(x^2+y)^n=\sum_{k=0}^n\binom{n}{k}x^{2n-2k}y^k\\
n=5\\
k=3\\\\\binom{5}{3}=\dfrac{5!}{3!2!}=\dfrac{4\cdor5}{2}=10$

It's 10.

----------------------------------------------------

$\displaystyle
(3x^2+y)^n=\sum_{k=0}^n\binom{n}{k}(3x)^{2n-2k}y^k=\sum_{k=0}^n\binom{n}{k}\cdot 3^{2n-2k}\cdot x^{2n-2k}y^k\\\\
n=5\\
k=4\\\\
\binom{5}{3}\cdot3^{2\cdot5-2\cdot4}=10\cdot3^{2}=10\cdot9=90$

It's 90
