Which of the following statements is true if m∠E = m∠Y and m∠F = m∠X? triangles EFG and YXZ in which triangle YXZ is larger than EFG m∠E > m∠Z ΔEFG ~ ΔYXZ The measure of each segment in ΔYXZ is three times the size of those in ΔEFG. There is a sequence of rigid motions that map ΔEFG onto ΔYXZ.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
