Answer:
5
Step-by-step explanation:
5 + 4 + 3 − 8 + 7 − 6
= 9 + 3 − 8 + 7 − 6
= 12 − 8 + 7 − 6
= 4 + 7 − 6
= 11 − 6
= 5
Answer:
A trinomial is an expression that has three terms.
Square trinomial
A square trinomial is simply a perfect square trinomial.
Difference of square binomials
This is easily identified because, the terms of the square binomials are perfect squares.
When cubes are added or subtracted, they can be expressed using the following
Answer:
P(2)=0 then x-2 is a factor of P(x)
Step-by-step explanation:
To see if (x-2) is a factor just plug in 2 for x into the polynomial expression.
2(2)^3-3(2)^2-17(2)+30
2(8)-3(4)-34+30
16-12-34+30
4-34+30
-30+30
0
Since P(2)=0 then x-2 is a factor
In order to solve for x in the equation <span>7x + 15 = 38, you must first subtract 15 from both sides.
</span><span>7x + 15 = 38
</span><span>7x + 15 - 15 = 38 - 15
7x = 23
Then you must divide so there is only 1x = a number. This can be done by dividing both sides by 7.
7x = 23
7x / 7 = 23 / 7
x ≈ </span>3.286
So the solution for x in the equation 7x + 15 = 38 is x ≈ 3.286.
Hope this helps!
Do you have answer choices? if not that’s okay but I did do the work and would be able to reply with the picture!
