So distribute using distributive property
a(b+c)=ab+ac so
split it up
(5x^2+4x-4)(4x^3-2x+6)=(5x^2)(4x^3-2x+6)+(4x)(4x^3-2x+6)+(-4)(4x^3-2x+6)=[(5x^2)(4x^3)+(5x^2)(-2x)+(5x^2)(6)]+[(4x)(4x^3)+(4x)(-2x)+(4x)(6)]+[(-4)(4x^3)+(-4)(-2x)+(-4)(6)]=(20x^5)+(-10x^3)+(30x^2)+(16x^4)+(-8x^2)+(24x)+(-16x^3)+(8x)+(-24)
group like terms
[20x^5]+[16x^4]+[-10x^3-16x^3]+[30x^2-8x^2]+[24x+8x]+[-24]=20x^5+16x^4-26x^3+22x^2+32x-24
the asnwer is 20x^5+16x^4-26x^3+22x^2+32x-24
Answer:
B
Step-by-step explanation:
A contrapositive statement is one that switches the hypothesis and conclusion of a conditional statement and negates both. In our hypothesis,
"If it is past 5:00 p.m., Megan’s office building is not empty", we shall break it into two statements and show the contarpositive of each like shown below.
Hypothesis Contrapositive
Megan’s office building is not empty- Megan’s office building is empty
It is past 5:00 p.m - it is not past 5:00 p.m
And thus the contrapositive statement becomes
If Megan’s office building is empty, then it is not past 5:00 p.m.
Make the equations equal to each other to find x.
21.2x+c=5.3(4x-4.6)
Now distribute.
21.2x+c=21.2x-24.38
So c= -24.38
Step-by-step explanation:
5(3x+2)-2(4x-1)
15x+10-8x+2
7x+12
