Answer:
-5t2 + 40t - 3
Step-by-step explanation:
Step-1 : Multiply the coefficient of the first term by the constant 5 • 3 = 15
Step-2 : Find two factors of 15 whose sum equals the coefficient of the middle term, which is -40 .
-15 + -1 = -16
-5 + -3 = -8
-3 + -5 = -8
-1 + -15 = -16
1 + 15 = 16
3 + 5 = 8
5 + 3 = 8
15 + 1 = 16
Answer: 4,000
Step-by-step explanation: 12,000 - 8,000 = 4,000 Hope it helped!! :)
MMK so saying that a=3 and b=4 means substitute the letters, with the numbers. I'm not gonna do it for you but ill help you out a bit.
5. 2(3)+8=
8. 7(3) x 9(4)=
11. 3^2 + 1=
14. (3)(4)/3=
I think you can do the rest on ur own my friend. Hope this helped :)
Answer: D
Explanation: to find whether two instances are proportional, find the rate of change for each situation. Simply divide both numbers from both situations and if the numbers are not the same they are not proportional.
X - first number
x + 36 - second number
x + (x + 36) = 40
2x + 36 = 40 <em>|subtract 36 from both sides</em>
2x = 4 <em> |divide both sides by 2</em>
<u /><u>x = 2</u>
x + 36 = 2 + 36 =<u> 38</u>
<em><u>Answer: 2 and 38.</u></em>
