y = 3x4 + 4x² – 5x + 10
Answer:
Solution:
(4x2 - 2x) - (-5x2 - 8x)
= 4x2 - 2x + 5x2 + 8x.
= 4x2 + 5x2 - 2x + 8x.
= 9x2 + 6x.
= 3x(3x + 2).
Answer: 3x(3x + 2)

The correct option is (B).
What is PEMDAS rule?PEMDAS: Order of Operations
P: Solve the calculation or equation which are present in the parentheses or brackets like small brackets( ), curly brackets{ } or big brackets[ ]. Priority is given to brackets first.
E: Exponential expressions should be calculated first before the operations of multiplication, division, addition and subtraction.
MD: Then perform multiplication or division from left to right, whichever comes first in the equation.
AS: At last, perform addition or subtraction whichever comes first while moving from left to right.
Given expression,
5 + 4 × 2
According to order of operations:
Solving multiplication operation:
5 + 8
Now solving addition operation
= 13
Hence, after applying order of operations, the value of expression is 13.

Jude has 30 coins of quarters and nickels. The total amount he has is $5.10. How many of each coin does Jude have? Write the system. Write the equations in the order that they appear in the problem.
Answer: Required system
x+y= 30
0.25x+0.05y=5.10
Jude has 18 quarters and 12 nickels.
Step-by-step explanation:
Let x= Number of quarters
y= Number of nickels
As per given,
x+y= 30 (i)
0.25x+0.05y=5.10 (ii) [1 quarter = $0.25 , 1 nickel = $0.05]
Multiply 0.25 on both sides of equation (i)
0.25x+0.25y= 7.5 (iii)
Eliminate (ii) from (iii) , we get
0.20y=2.4
⇒ y = 12 [divide both sides by 0.20]
Put value of y in (i\), we get
x+12=30
⇒ x= 30-12= 18
Hence, Jude has 18 quarters and 12 nickels.
