Ivanshal [37]

Answer: A = 117 units^2

Step-by-step explanation: If you cut the shaded region in half it's two rectangles so you have to find the area of it using the formula to find the area of a rectangle.

A = (w)(l)                                                                                                                   A = (9)(13)                                                                                                               A = 117 units^2

Explain why solving the equation - 3n - 4 = 2 is different from solving the
Klio2033 [76]

Answer:

Step-by-step explanation:

First get the answer to -3n - 4 = 2

-3n - 4 + 4 = 2 + 4

-3n = 6

n = 6/-3

n = -2

That answer is the only one that is permitted. It is the only one that completely satisfies the equation.

Now when you do the inequality, look what happens.

-3n - 4 < 2              Add 4 to both sides.

-3n-4+ 4 < 2+4

-3n < 6                  Now there are a bunch of ways (2) to solve this.  

                            No matter which way you do it, the arrow will change.

-3n/-3 > 6/-3

n > - 2

That means that any number that is greater than - 2 will satisfy the inequality.

So n = 0 will work. Even n = - 1 will work. Anything bigger than -2 will work. The equation does not provide that kind of latitude.

If x+y=4a+7 and x-y=2a+5, solve for x in terms of a
oksian1 [2.3K]

Answer:

A

Step-by-step explanation:

x + y = 4a + 7

x - y = 2a + 5

In both equations, make x the subject of the formula

x = 4a + 7 - y equation 1  

x = 2a + 5 + y equation 2

Subtract equation 2 from equation 1

2a + 2 -2y

= 2a + 2
