Answer:
5 points
Step-by-step explanation:
Alice, Bianca, Camila, and Dasha each scored 14 points. 14 x 4 = 56
56 + 15 = 71
3 x 5 = 15
The three remaining girls scored 5 points each.
Step-by-step explanation:
By binomial theorem,
T(r+1) = nCr * a^(r+1) * b^r
Term 4 = 7C3 * (2x)^4 * (-5y)^3 = 35 * (16x^4) * (-125y^3) = -70000x^4y^3.
Answer: Three plus Five equals Eight or 3= a · 5= 5a
Step-by-step explanation:
Answer: first question answer is 3x^3+6x^2-24x+27
Second question answer=a^2-ab
Step-by-step explanation:
Answer:
1.25 would be the leading coefficient
Step-by-step explanation:
Leading coefficients in scientific notation have to be more than 1, and less than 10. Therefore, 12.5 or 0.125 would not be correct answers as they do not fit the criteria. Only 1.25 would work as the leading coefficient.
