Answer:
38,710.
Step-by-step explanation:
This is an arithmetic series with common difference 8 , first term a = 7 and last term L = 783.
The number of terms n = (783 - 7) / 8 + 1 = 98
Sum of 98 terms = (n/2)[a + L)
= (98/2)(7 + 783)
= 49 * 790
= 38,710.
Answer:
my guy did you repost this as I just answered this about ten minutes ago
All except 2(50+10)
Because 50+10=60 • 2 =120
And 100+20=120
Answer:
k = 77
Step-by-step explanation:
To order the polynomial - x^4y^2+7x^3y^3-3xy^5+2x^2y^4 in descending powers of x, we must take into account the powers of the
x. We must start with the term that has the highest degree and end with the
term that has the lowest grade.
Finally, when we order the polynomial -x^4y^2+7x^3y^3-3xy^5+2x^2y^4, we get:
-x^4y^2+7x^3y^3+2x^2y^4-3xy^5
