I don't know the area of a parallelogram off the top of my head but you can use the area of the rectangle and the area of the triangle and add those. The area of the triangle is 1/2*base*height and use the pythagorean theorem to find the base. 3² + b² = 5²; 9 + b² = 25; b² = 16; b = 4. The area of the triangle is 1/2*4*3 or 6 in. Since there are two of them, the total area of the triangles are 12 in. The area of the rectangle is length*width or (12 - 4) * 3 which is 8 * 3 or 24in. Add these areas together to get 36in total

Given that r= 2p2/q-3 ; rearrange the formula to make q the subject of the formula.

Vesnalui [34]

Step-by-step explanation:

The given expression is:

$r=\dfrac{2p^2}{q-3}$

We need to solve it to make q the subject of the formula.

Cross multiplying both sides,

$rq-3r=2p^2$

Adding 3r to both sides,

$rq-3r+3r=2p^2+3r\\\\rq=2p^2+3r$

Now, dividing both sides by r,

$q=\dfrac{2p^2+3r}{r}$

Hence, this is the required solution.

The reduced row echelon form of a system of linear equations is given. Write the system of equations corresponding to the given

morpeh [17]

Answer:

a. x +8z = -1

b. y +5z = 2

c. 0 = 0

d. (x, y, z) = (-1-8z, 2-5z, z)

Step-by-step explanation:

As with the original matrix, the first three columns are the coefficients of the respective variables, and the last column is the constant on the right of the equal sign.

a. The first row represents the equation ...

x + 8z = -1

b. The second row represents the equation ...

y + 5z = 2

c. The third row represents the equation ...

0 = 0

This equation expresses a truth, so indicates the original system of equations was consistent, but dependent. (a third row of 0 0 0 1 would indicate inconsistent, no solution)

d. The system is consistent but dependent. The solution can be written as ...

(x, y, z) = (-1-8z, 2-5z, z) . . . . where z is a free variable
