Answer:
Quadratic trinomial
Step-by-step explanation:
It is a trinomial because it has 3 terms.
Quadratic means the highest exponent is 2.
These are so easy, you won't believe it !
A negative exponent only means
"Put all of this in the denominator, and make the exponent positive."
So (any number)^negative power =
1 / (the same number)^(the same power but not negative) .
The first few problems on that sheet:
1). 5^-3 = 1 / 5^3
2). 6^-10 = 1 / 6^10
3). (-2)^-5 = 1 / (-2)^5
Got it ? You can do the rest of them now in about 2 minutes.
Answer:
4
Step-by-step explanation:
The equation is 2(10+x)=28 where x is the unknown number we are trying to find. Use distrubutive property to combine like terms. 2 times 10 is 20 and 2 times x is 2x. Now we have 20+2x = 28. What you do to one side you must do to the other. 20 minus 20 is 0. 28 minus 20 is 8. Now our equation is 2x is 8. To find 1 x we divided in half. 8/2 is 4 therefore the missing variable is 4.
This is probably wrong but i think it’s 3,528 hope everyone has a good day
Answer:
x = 16
Step-by-step explanation:
2x + (3x-6) = 74
5x -6 = 74
5x = 74 + 6
5x = 80
x = 16
