In a theatre room, there are 4 rows of chairs. There are 4 columns of chairs. How many chairs are there in the theatre room?
4x4=16
There are 16 chairs in the theatre room.
Step-by-step explanation:
given
a = - 3
3a² = 3 * ( -3) ²
= 3 * 9
= 27
The value of 3a² is 27.
approx 1 foot
The area (A) of a circle = πr² ( where r is the radius)
thus r² = A/π ⇒ r = √(A/π = √(3.21/π) =1.0108..... ≈ 1 foot ( to 1 dec. place)
The value of m from the equation is -1/5
<h3>Solving equations and expression</h3>
Given the equation below expressed as;
3(5m + 2) = 3
Expand
3(5m) + 3(2) = 3
15m + 6 = 3
Subtract 6 from both sides
15m + 6 - 6 = 3 - 6
15m = -3
Divide both sides by 15
15m/15 = -3/15
m = -1/5
Hence the value of m from the equation is -1/5
