A rectangle has a length of 6x +3 units and a width of 8 units. Part A: Write a simplified expression for the area, in square un
frutty [35]

Answer:

a) A = 48x + 24

b) Yes

Step-by-step explanation:

a) The area of a rectangle is found using A = l*w. Substitute l = 6x + 3 and w = 8 to find the area.

A = (6x + 3)(8) = 48x + 24

b) Repeat the same process with the formula A = l*w. Substitute l = 4x + 2 and w = 12.

A = (4x+2)(12) = 48x + 24

The areas are the same.

If angle 0 is in quadrant I, what is the value of
Brilliant_brown [7]

Answer:

the \: answer \: is \: c \:  =  -  \frac{ \sqrt{14} }{5}

Step-by-step explanation:

\sin^{2}0 + ( \frac{ \sqrt{11} }{5} ) ^{2}  = 1( \sin^{2}0 +  \cos^{2} 0 = 1)

{ \sin }^{2}0 +  \frac{11}{25} = 1   \\  { \sin }^{2}0 =  \frac{14}{25}

\sin0_{1} =  -  \frac{ \sqrt{14}}{5} while \sin0_{2} =  \frac{ \sqrt{14} }{5}

  • Therfore theta is QI
  • Therfore sin theta >0
  • therefore \:  \sin0 =  \frac{ \sqrt{14} }{5}
