Answer:

5

Step-by-step explanation:

Segments are named by their endpoints. Therefore, segment PQ will have endpoints P and Q. The length of the segment is equal to the distance between these points.

To find the distance between P and Q given their coordinates, use the distance formula:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Let:

P(-2, 7)\implies (x_1, y_1),\\Q(1, 3)\implies (x_2, y_2)

The distance between these points is equal to:

d=\sqrt{(1-(-2))^2+(3-7)^2},\\d=\sqrt{3^2+(-4)^2},\\d=\sqrt{9+16},\\d=\sqrt{25},\\d=\boxed{5}

Answer:

5

Step-by-step explanation:

This problem gives one the following points on a line: (P(-2,7)), and (Q(1,3)). The problem asks one to find the distance between the two points. The formula to find the distance between two points on a coordinate point is the following,

D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Substitute the given values in and solve for the distance;

D=\sqrt{(-2)-(1))^2+((7)-(3))^2}

Simplify,

D=\sqrt{(-2)-(1))^2+((7)-(3))^2}\\\\D=\sqrt{(-3)^2+(4)^2}\\\\D=\sqrt{9+16}\\\\D=\sqrt{25}\\\\D = 5

Fern rounded to the nearest ten to estimate 548-132. She subtracted 540-130 and got 410. Is Fern's estimate correct? Explain.
tensa zangetsu [6.8K]
Fern's estimate is not correct because he rounded 548 wrong, it would be rounded to 550 instead since the number 8 is closer to 10. So the correct answer would be 420.

Let L be the length
Let w be the width
Let p be the perimeter
L+w+L+w=p
L=w+20
3L+2w+3L+2w=240
Sub the first equation in for L in the second equation and solve for w
3(w+20)+2w+3(w+20)+2w=240
3w+60+2w+3w+60+2w=240
10w+120=240
10w=240-120
10w=120
W=120/10
W=12
Sub w into the first equation and solve for L
L=w+20
L=12+20
L=32
Hope this helps!
