Answer:
By adding 4 to both sides.
2= -4 +b
2= b -4
2+4= b-4 +4
6= b
Another way to look at it is to move all the constants to one side. Here we have the constant 2 on the left hand side, and on the right we have the constant -4 and the variable b.
To isolate b, we move the constant -4 to the left hand side. Moving a number to the other side of the equal sign changes the sign of the number. So, -4 becomes a +4 on the left hand side.
2 +4= b
6= b
Answer:
30 cm
Step-by-step explanation:
Perimeter = (half the circumference) + (twice the radius)
= (1/2)(2·10 cm) + 2(10 cm)
= 10 cm + 20 cm
= 30 cm
In a triangle, the three interior angles always add to 180°
x = 180 - 101 - 28 = 51°
It’s going to be 4y(3x^2-8x+2) because 4 is the biggest factor that can go into 32,12, and 8.
