Let x inch be the width
x×2+(x+7)×2=34
2x+2x+14=34
4x=20
x=5
the length=5+7 i.e.12 inches
the width=5 inches
Area=5×12=60 inches
The answers are
a) the domain is all real numbers
d) the input to an exponential function is the exponent
e) the base represents the multiplicative rate of change
hope this helps :)
Answer:
x=25, 120
Step-by-step explanation:
The two angles form a straight line so they add to 180
60 + 4x +20 =180
Combine like terms
4x+80 = 180
Subtract 80 from each side
4x+80-80 =180-80
4x= 100
Divide by 4
4x/4 =100/4
x= 25
The exterior angle is
4x+20 = 4*25+20 =100+20 =120
