Answer:

MN = b - a

Step-by-step explanation:

N = \frac{1}{2}BA

BA = a - b = 4a - 2b

\frac{1}{2}BA = \frac{1}{2} (4a - 2b) = 2a - b

Thus

MN = MO + OB + \frac{1}{2} BA

      = - 3a + 2b + 2a - b

     = b - a

Answer:

b+3a

Step-by-step explanation:

MN=AN+AM

AN=0.5*AB

AB=OA+OB=4a+2b

AN=2a+b

AM=OA-OM=4a-3a=a

MN=2a+b+a=3a+b

Express the equation x = 10 and y = -3 as a linear equation in two variables
34kurt

Answer:

For x = 10:

x + 0y - 10 = 0

For y = - 3:

0x + y + 3 = 0

Step-by-step Explanation:

Before we start let's recall the formula for the linear equations.

ax + bx = c

So first let's solve for x=10:

x = 10

Move 10 to the other side.

x - 10 = 0

As there is no y given we will simply write 0y.

x + 0y  - 10= 0

Now let's solve for y=-3:

y =  - 3

Move -3 to the other side.

y + 3 = 0

As there is no x given we will simply write 0x.

0x + y + 3 = 0

Answer: The dimensions of the frame:.

W= 2√10 or about 6.3245 inches

L= 4√10 or about 12.6491 inches

Step-by-step explanation:

This would be so much easier if the area of the box was 72. Then the dimensions of the frame would be 6 × 12. So just a little bit larger and more complicated.

Here the equation is w(2w)=80

2w^2 = 80 (2w is easier to work with than L/2).

w^2=40 (^2 means squared)

√w^2 = √40 square root of both sides: Factor 40. Take out√4

W = √4*10

W= 2√10

L= 2w = 4√10

6.3245 × 12.6491 = 80
