Answer:
Width=9.5, Length=32.5
Step-by-step explanation:
Let x be the width of the rectangle,
The length is 4 feet more than 3 times the width,
The length= 3x+4
The perimeter is
2(x)+2(3x+4)=84
2x+6x+8=84
8x=76
x=76/8
x=9.5
The Width=9.5
Length= 3(9.5)+4=32.5
A^3 + 3a^2 b - 4ab - 11b + 7 has five terms.
Answer:
x=30° y=110°
Step-by-step explanation:
80+70=150
180-150=30° 》》》》 angles in a triangle add up to 180°
x=30° opposite angles are equal
180-140=40° angles on a straight line add up to 180°
30+ 40=70
180-70=110°
y=110°
$990
550 x .80 = 440
$550 + $440 = $990
D because you would subtract the initial value from the finals value and you get 250, than you would divide it by the initial value and get .25, than you would multiply it by 100 and you would get 25%
