Answer:
DF=13
Step-by-step explanation:
DE+EF=DF
2x+3+4=3x+4
2x+7=3x+4
7-4=3x-2x
x=3
DF=3x+4
DF=3(3)+4
the rate growed so they are more rapes now than the past decade
Infinitely many
12x + 1 = 3(4x + 1) - 2
12x + 1 = 12x + 3 - 2
12x + 1 = 12x + 1
Both sides are equal for all x, so infinite solutions
x and 52 are supplementary, so they add up to 180°
