The sum of the squares of two consecutive negative integers is 61. Find the smaller of the two integers

Marysya12 [62]

$x^2+(x+1)^2=61\\ x^2+x^2+2x+1-61=0\\ 2x^2+2x-60=0\ \ /:2\\ x^2+x-30=0\\ \Delta=1^2-4\cdot(-40)=1+120=121\ \ \Rightarrow\ \ \sqrt{\Delta} =11\\ \\ x_1= \frac{-1-11}{2} = \frac{-12}{2} =-6,\ \ \ \ x_2= \frac{-1+11}{2} = \frac{10}{2}=5\\ \\Ans.:x=-6$

How do you simplify the value of (28x^4)÷(12x^3)?

d1i1m1o1n [39]

$(28x^4) \div (12x^3) = \dfrac{28x^4}{12x^3} = \dfrac{4 \times 7x^4}{4 \times 3 x^3} = \dfrac{7}{3} x^{4-3} = \dfrac{7}{3} x$

Martin is interested in the effects of different kinds of instruction on videogame performance. Martin asks 30 college freshmen

777dan777 [17]

Answer:

Between - groups variance

Step-by-step explanation:

From the question we see that the college freshmen are assigned to one of the three given groups. This means that they are exposed to different experimental conditions and thus it means that the variation differs as a result of different experimental conditions between the groups.

Thus, these differences reflect between - group variance.
