The length of a rectangle is the sum of the width and 3. The area of the rectangle is 54 units. What is the width, in units, of
the rectangle?

Answer:
Step-by-step explanation:
let width=x
length=x+3
x(x+3)=54
x²+3x-54=0
x²+9x-6x-54=0
x(x+9)-6(x+9)=0
(x+9)(x-6)=0
x=-9,6
x=-9 (rejected)
as width can't be negative.
hence width=6 units

Answer: 2
Step-by-step explanation:
Interior angles of a triangle should always add up to 180.
180-154=26
26-13=13
X=13
Answer:
because when the value of x is replaced in the factorisation it Will be equivalent to 100
Distribute the -2 to get
-16x + 8 < 2x + 5
3 < 18x
1/6 < x
so x > 1/6
The area of a rectangle is easy to compute.
Area = length times height
Area = 8 cm * 4 cm = 32 square centimeters
