For any triangle, the sum of its interior angles will be equal to 180°

From there, we can make the next equation:

x + 51 + x + 73 + 72= 180

In this equation, I will simplify on the left, adding 51, 73 and 72.

2x + 196 = 180

Now I will subtract 196 on both sides.

2x = 180 - 196

2x = -16

Next, I will divide by 2 on both sides.

x = -16 / 2

x = -8

Now that I have the value of x, I can solve for A

A = x + 73

A = -8 + 73

A = 65°

I have no idea what to do with this!

The function given in the question is

g(x) = 4x - 5
When x = 2, then
g(2) = (4 * 2) - 5
= 8 -5
= 3
When x = - 4, then
g(-4) = (4 * -4) - 5
= - 16 - 5
= - 21
From the above deduction, it can be concluded that the correct option among all the options given in the question is the third option or "The value of g(2) is larger than the value of g(-4)". I hope that the procedure is clear enough for you to understand.

7. Which dimensions result in the minimum perimeter for a rectangle with area 42.0 cm2?

Answer:

7. d. l = 6.48 cm, w = 6.48 cm

8. d. square

Step-by-step explanation:

For a given area, the perimeter can always be shortened by reducing the length of the long side and increasing the length of the short side. When you get to the point where you can't do that, then you have the minimum perimeter. You will reach that point when the sides are the same length: the rectangle is a square.

7. In light of the above, the best dimensions are √42 ≈ 6.48 cm for length and width.

8. In light of the above, the shape is a square.

_____

The attached graph shows the length of one side (x) and the associated perimeter. The other side is 42/x, which will also be 6.48.
