Greg has enough framing to enclose a rectangular photograph with a perimeter of 160 centimeters. If the width of his photograph

kotegsom [21]

Answer:

32cm

Step-by-step explanation:

Let the width be w. Now we know that the width is 16cm less than the length, this means that the length will thus have a total length of w + 16

Now, we know that the perimeter of a rectangle is 2(l + b)

This means 2(w + w + 16) = 160

4w + 32 = 160

4w = 128

w = 128/4 = 32cm

What is The midpoint of AB=(1,

BigorU [14]

The midpoint of AB is point G

<h2>Explanation:</h2>

The complete question has been attached below. As you can see, we have a line segment which is defined as a part of a line that is bounded by two different points that are at the end of the segment. So here we know that:

A is located at point -6.
B is located at point 8

Therefore, the midpoint can be calculated as:

$M:midpoint \\ \\ \\ M=\frac{A+B}{2} \\ \\ M=\frac{-6+8}{2} \\ \\ M=1$

So the midpoint is $M=1$ that matches point G. Finally:

Conclusion: The midpoint of AB is point G

On a coordinate plane, if you take a point from (2, -5) and move it up 3 units to point "A" what is the distance of point a to c

tamaranim1 [39]

Answer:

Step-by-step explanation:

(2,-5) move up three steps is (2, -2). if you draw it on a paper(and draw lines to connect them), you can see that they form a right triangle. apply a²+b²=c² and you should get 3²+2²=(√13)²
