Expand the expression?
Perform indicated multiplication:
7a(2a)+7a(-5)-4(2a)-4(-5)
14a^2-35a-8a+20 combine like terms, ie (-35a-8a)=-43a
14a^2-43a+20
Answer:
D
Step-by-step explanation:
x²-4x-12≤0
x²-6x+2x-12≤0
x(x-6)+2(x-6)≤0
(x-6)(x+2)≤0
x=6,-2
∴ value of x lies between -2 & 6
Answer:
its sophisticated but answer is 3
Step-by-step explanation:
you have to dive deep into it and research
You have to do 12 times 4, which equals 48. So 48 pounds in a year. 105 plus 48 would be 153 so that would be his weight by next year
