Answer:

Area of a triangle

$\frac{bh}{2} \\ 10 \times 10 = 100 \\ 100 \div 2 = 50 \\ the \: triangles \: have \: the \: same \: area \: and \: there \: are \: 4 \: triangles \: so \\ 4(50) = 200 \\ now \: we \: find \: the \: are \: of \: the \: rectangular\: base \: \\ area = bh \\ b = 10 \\ h = 10 \\ 10(10) = 100 \\ no w \: we \: add \: the \: area \: of \: the \: triangles \: and \: the \: square \\ 200 + 100 = 300 \: {in}^{2}$

Solve for N. <br> 2[7-6(1-n)]+3n=-20+4[6(n+1)-3n]

jonny [76]

Solving the expression $2[7-6(1-n)]+3n=-20+4[6(n+1)-3n]$ we get $n=\frac{2}{3}$

Step-by-step explanation:

We need to solve the equation $2[7-6(1-n)]+3n=-20+4[6(n+1)-3n]$ and find value of n.

Solving:

$2[7-6(1-n)]+3n=-20+4[6(n+1)-3n]$

Multiplying the terms inside the bracket

$2[7-6+6n]+3n=-20+4[6n+6-3n]$

Simplifying:

$2[1+6n]+3n=-20+4[6n-3n+6]$

$2[1+6n]+3n=-20+4[3n+6]$

$2+12n+3n=-20+12n+24$

$2+15n=12n+4$

Adding -12n and -2 on both sides

$15n-12n=4-2$

$3n=2$

$n=\frac{2}{3}$

So, Solving the expression $2[7-6(1-n)]+3n=-20+4[6(n+1)-3n]$ we get $n=\frac{2}{3}$
