Answer:
All the sides of a rhombus are equal and opposite sides parallel and equal.
Therefore by understanding the above we can deduce that:
7x - 4 = 5x + 4
7x - 4 + 4 - 5x = 5x + 4 + 4 - 5x (Separate all the terms with x to go to the other side of the equals sign and do the some for the constants).
7x - 5x + (4 - 4) = (5x - 5x) + 4 + 4
7x - 5x = 4 + 4
2x = 8
2x/2 = 8/2
x = 4
According to the question, we are to complete a 2-column proof to show that the measure of BC is equal to EF:
Given the following:
AC = AB + BC....................... 1
AC = AB + x ............... 2
From equation 2, AB = AC - x ................. 3
Substitute equation 3 into 1:
AC = AB + BC
AC = AC-x + BC
AC-AC = -c + BC
0 = -x + BC
BC = x
Since AC is greater than AB by a value of x, hence AC > BC

Answer:
f(- 10) = 74
Step-by-step explanation:
To find f(- 10) , substitute n = - 10 into f(n) , that is
f(- 10) = - 7(- 10) + 4 = 70 + 4 = 74
