Step-by-step explanation:
G is the centeroid of the triangle. G splits AE in the ratio 2 : 1
AG : GE = 2 : 1
AG = 2x and GE = x
2x = 20
x = 20/2
x = 10
GE = 10 ; AG = 20
AE = 20+10 = 30
CG : GD = 2:1
CG = 2x and GD = x
2x = 10
x = 10/2
x = 5
GD = 5
BF = 30
BG : GF = 2 : 1
BG = 2x ; GF = x
BF = 30
BG + GF = 30
2x + x = 30
3x = 30
x = 30/3
x = 10
GF = 10
Answer:
true
Step-by-step explanation:
if an object is losing heat energy, it turns cold, and can turn into a solid, for example, water turning into ice. If you apply heat on ice, it's turns back to water. IF you apply heat to water, it vaporizes, and turns into gas.

2.47 + 7.1 = 9.57
7.1 + 2.47 = 9.57
9.57 - 2.47 = 7.1
9.57 - 7.1 = 2.47
<u>Explanation</u>
A fact family is a group of math facts using the same numbers. In the case of addition/subtraction, you use three numbers and get four facts.
In this case we are going to write two different addition facts and two different subtraction facts as follows:
2.47,9.57,and 7.1
<em><u>Addition facts</u></em>
2.47 + 7.1 = 9.57
7.1 + 2.47 = 9.57
<em><u>Subtraction</u></em>
9.57 - 2.47 = 7.1
9.57 - 7.1 = 2.47
