Step-by-step explanation:

6x-2y=5 ........... Equation 1

y=3x+7 ............. Equation 2

Substitute y that's Equation 2 into equation 1 and solve for x

That's

6x - 2( 3x + 7) = 5

6x - 6x - 14 = 5

6x - 6x = 14 + 5

6x - 6x = 19

0x = 19

Divide by 0

x is undefined

Since x is undefined y is also undefined which means that the system has no solutions

Hope this helps you

If a 4 x 16 riangle has the same area as a square, what is the length of a side of the square

m_a_m_a [10]

Answer: $\bold{4\sqrt2}$

<u>Step-by-step explanation:</u>

$A_{triangle}=\bigg(\dfrac{1}{2}\bigg)b\times h$

$A_{triangle}=\bigg(\dfrac{1}{2}\bigg)4\times 16$

$=\bigg(\dfrac{1}{2}\bigg)64$

$=32$

$A_{square}= s^2$

$32 = s^2$

$\sqrt{32}=s$

$\sqrt{\underline{2\cdot 2}\cdot \underline{2\cdot 2}\cdot 2}=s$

$2\cdot 2\sqrt{2}=s$

$4\sqrt{2}=s$
