What terms govern the length of this side?The basic rule of the triangle.First side length must be less than the sum of the other two sides.So to find X we must take the largest side of the triangles and compare them with amounts from other sides.

5+x>12
8+x>20    and it's system

x>7
x>12
general solution is x>12
<span>The least possible integral is 13.

PS: It's may be </span>yet 12, but in this case, triangle  BCD become segment.

What is the slope of the line that passes through the points (4, 7) and (8, 9)
SSSSS [86.1K]

Answer:

y = 0.5x + 5

Step-by-step explanation:

Use the slope formula to find the slope of a line given the coordinates of two points on the line.

The slope formula is:

m = \frac{y{2}-y{1}  }{x{2}- x{1} } = \frac{y}{x}

The coordinates of the first point represent x1 and y1. The coordinates of the second points are x2, y2.

Now let's fill in the formula with the points,

m = \frac{8-4}{9-7}

Solve,

⇒ Y = 9 – 7 = 2

⇒ X = 8 – 4 = 4

m = \frac{8-4}{9-7} = \frac{2}{4}

Simplify,

⇒ \frac{2}{4}=\frac{1}{2}=0.5

Therefore, the Equation of the line is y = 0.5x + 5.

Inessa [10]

Answer:

152

Step-by-step explanation:

So first I find the area of the big rectangle going down, which is 14x8=112

And then I do the flap thingies on the side: 5x4=20x2=40

112+40=152
