Answer: 147 cm²
Step-by-step explanation:
Since it says to use 3 for pi, and the radius is given to us (7 cm), we will plug in and solve for the area.
A = πr²
A = (3)(7)²
A = 147 cm²
All real numbers
distribute (x+6)(x+3) to get x^2+6x+3x+18
your equation now looks like this:
x^2+6x+3x+18= x^2+6x+3x+18
because the equations are equal, the answer is all real numbers
Well if you calculate it by using 160 over 1 and 1 over 4 the quotient is 640.
Answer:
The Answer would be The first ab
Step-by-step explanation:
Angle 3:
62+47=109
All angles in a triangle add to 180 degrees, so 180-109= 71 degrees
Angle 2:
Angles in a straight line always add to 180 degrees too,
so 180-62= 118 degrees
Angle 1:
Again, angles in a triangle add to 180,
so 180-22-118= 40 degrees
Angle 1: 40
Angle 2: 118
Angle 3: 71
Hope that helps :)
