This is just the perimeter so add all of the numbers up. 4.2 + 9.4 + 4.6 + 5.6 = 23.8.

Multiply 23.8 by 7.4 to convert it to meters. 23.8 X 7.4 =171.36

Answer:

2√(5)

Step-by-step explanation:

Since it's stated that thegiven is right triangle :

The square length of hypotenus (the side lenght that sees 90 degrees) is equal to sum of square length of side lengths

2^2 + 4^2 = x^2

4 + 16 = x^2

20 = x^2 and x = 2√(5)

The only thing you need to do is divide 56 by -7. You know the d must be a negative number because negative x negative= positive. So 56 / -7 is -8.

ſ x - 5y = -9( 4x + 4y = - 12Step 1 of 2: Determine if the point (-4,1) lies on both of the lines in the system of equations by

Phoenix [80]

Given:

$\begin{gathered} x-5y=-9\ldots\ldots(1) \\ 4x+4y=-12\ldots\text{.}\mathrm{}(2) \end{gathered}$

The given point is (-4,1)

Let's check the ordered pair (-4,1) in the first equation

$\begin{gathered} x-5y=-9 \\ (-4)-5(1)=-9 \\ -4-5=-9 \\ -9=-9 \end{gathered}$

Hence, (-4,1) is a solution of the first equation x-5y=-9.

Now, let's check (-4,1) in the second equation.

$\begin{gathered} 4x+4y=-12 \\ 4(-4)+4(1)=-12 \\ -16+4=-12 \\ -12=-12 \end{gathered}$

So, (-4,1) is a solution of the second equation 4x+4y=-12.

Hence, (-4,1) is a solution of both equation in the system, then it is a solution to the overall system.
