HELP PLEASE!

Answers:

\text{Perimeter} = 14\sqrt{5}\\\\\text{Area} = 50\\\\

=======================================================

Work Shown:

L = 2\sqrt{5} = \text{length}

W = 5\sqrt{5} = \text{width}

P = perimeter

P = 2*(L+W)\\\\P = 2*(2\sqrt{5}+5\sqrt{5})\\\\P = 2*(7\sqrt{5})\\\\P = 14\sqrt{5}\\\\

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

A = area

A = L*W\\\\A = (2\sqrt{5})*(5\sqrt{5})\\\\A = (2*5)(\sqrt{5}*\sqrt{5})\\\\A = 10\sqrt{5*5}\\\\A = 10\sqrt{25}\\\\A = 10*5\\\\A = 50\\\\

If f(x) = 7 + 4x and g(x)= 7x, what is the value of (f/g)(5)
andrew-mc [135]

The value of (\frac{f}{g})(5) is \frac{27}{35}

Explanation:

Given that f(x)=7+4x and g(x)=7x

<u>The value of </u>(\frac{f}{g})(5)<u>:</u>

The value of (\frac{f}{g})(5) can be determined by substituting x = 5 in the functions f(x) and g(x) and then dividing the terms, we get, the value of (\frac{f}{g})(5)

Thus, we have,

(\frac{f}{g})(5)=\frac{f(5)}{g(5)}

Substituting the value of x = 5 in the functions f(x) and g(x), we get,

(\frac{f}{g})(5)=\frac{7+4(5)}{7(5)}

Simplifying the terms, we have,

(\frac{f}{g})(5)=\frac{7+20}{35}

Adding the terms in numerator, we have,

(\frac{f}{g})(5)=\frac{27}{35}

Thus, the value of (\frac{f}{g})(5) is \frac{27}{35}

3x - y = -4
_________
0x -5y = -5

y = -5/-5 = 1

Plug 1 in for y in either of the equations

3x -1 = -4
3x = -3
x = -1

Answer: (-1, 1)
