The perfect square monomial and its square root are shown in options 1, 2, and 5.
- A perfect square in mathematics is an expression that factors into two equally valid expressions. A monomial is a single phrase that is made up of the product of positive integer powers of the constants, variables, and constants. Consequently, a monomial that factors into two monomials that are the same is called a perfect square monomial.
- 1) 121, 11
- 11² = 121
- A perfect square monomial and its square root are represented by this equation.
- 2) 4x², 2x
- (2x)² = 4x²
- A perfect square monomial and its square root are represented by this equation.
- 3) 9x²-1, 3x-1
- (3x-1)² = 9x²- 6x +1
- This phrase does not depict a square monomial and its square root in perfect form.
- 4) 25x, 5x
- (5x)² = 25x²
- This phrase does not depict a square monomial and its square root in perfect form.
- 5) 49(x^4), 7x²
- (7x²)² = 49(x^4)
- A perfect square monomial and its square root are represented by this equation.

<span>twice the sum of a number and seven is 8
2(x+7)=8</span>
Step-by-step explanation:
Number of green and white jelly beans
= Number of green + Number of white
= 4 + 2 = 6.
Probability = Number of green and white jelly beans / Total number of jelly beans * 100%
= 6 / (4 + 2 + 5) * 100% = 54.55%.
A=4,706×(1+0.04÷4)^(4×4)
A=5,518.16
Interest earned=5518.16-4706=812.16
