Answer:
Fourth option
Step-by-step explanation:
Given the expression in the picture:
Apply Power of Power Rule


The left side of the equation option had this in the fourth option so the fourth option is right
N(2n+6)-(n²-1)= 2n²+6n-n²+1=n²+6n+1
Percent is parts out of 100 so
45%=45/100=9/20
'of' means multiply
18 =9/20 times something
multiply both sides by 20/9 to clear fraction
360/9=something
40=something
the value is 40
First you want to write 7x as a sum or difference: 15x-8x
Now, the expression would look like this: 10x^2+15x-8x-12
Next, factor out the 5x and -4 from the expression: 5x(2x+3)-4(2x+3)
Now, factor out the 2x+3 from the expression and you have your answer:
(2x+3)(5x-4)
