You would need to subtract 18 to both sides to make this a perfect-square trinominal.
x^2 - 12x = 18
x^2 - 12x - 18 = 0
a = 1
b = -12
c = -18
Best of Luck!
28 blue fish I think you just subtract 3 by 31
Answer:
25m/s
Step-by-step explanation:
Here,
Initial velocity(u) = 5.0 m/s2
acceleration(a)= 2m/s2
time taken(t)=10.0 s
final velocity (v)=?
Now,
v=u+at
=5.0+2*10.0
= 25m/s

The area of semi-circle is 8π cm² with diameter of 8cm.
What is area of semi-circle?
- The area that the semicircle occupies is that which is contained inside its perimeter. Half of a circle is a semicircle.
- The area of a semicircle will therefore be equal to half that of a circle. Both the radius and the diameter can be used to get the semicircle's area.
- The formula used to determine a semicircle's area in terms of radius "r" is written as follows:
Area of circle = πr²/2
- Area of semi-circle= πd²/8 is the formula used to determine a semicircle's area in terms of its diameter.
- The value of the constant is 22/7, or 3.14.
Given:
Diameter = 8cm
Area of semicircle = πd² / 8
=π8² / 8
= 8π cm²
Hence, the area of semi-circle is 8π cm².
