Area=base*height
A=(x+6)(2x+2)
A=2(x+1)(x+6) technically this is the simplified form, but they may want the expanded form...
A=2x^2+14x+12
Answer:
C
Step-by-step explanation:
Since the number outside of the parentheses is -5, the negative factor means that the line is reflected across the x-axis.
Step-by-step explanation:
EF = 4x - 15
FG = 3x - 7
EG = EF + FG = 20
so,
4x - 15 + 3x - 7 = 20
7x - 22 = 20
7x = 42
x = 6
EF = 4×6 - 15 = 9
FG = 3×6 - 7 = 11
Substitute -3 to the function equation where x found . therefore it will be 19--3=22. the final answer is 22
