Answer:
Please check the explanation.
Step-by-step explanation:
Given the expression
Apply exponent rule: 
∵ 
Factor out common term 2y
We know that the Binomial is an expression that consists of two terms. Thus,
(4x²y²- 9) represents the binomial factor of
We can further simplify by Factoring 4x²y² - 9: (2xy + 3) (2xy - 3)
Here:
(2xy + 3) and (2xy -3) are the binomial factors of as each of them consists of two terms.
Answer:
80
Step-by-step explanation:
20 percent is 16 questions
then 100/20=5
5 times 16 is 80
Answer:

Answer:
C. 65
Step-by-step explanation:
Compare to the standard form ...
ax² +bx +c
to find the values of a, b, c. They are ...
a=2, b=3, c=-7
The discriminant is ...
d = b² -4ac
d = (3)² -4(2)(-7) = 9 +56
d = 65 . . . . . . matches choice C
The figure that is not equivalent to 2¾ is 2¼ × 2½. That is option B.
<h3>Simplification of equivalent fractions</h3>
Simplification is a process that is used to make a fraction appear in its simplest forms.
The fraction given is = 2¾
The simplification of the fraction= 2^3/4 = 2
But simplification of 2¼ × 2½ is equal to;
2¼= 0.5
2½= 1
Therefore 2¾ is not equivalent to 2¼ × 2½ when simplified.
