Step-by-step explanation:
x2 + 2xn + n2
x2 + xn + xn + n2
x(x + n) + n (x + n)
So (x + n)^2 is the factor
Answer:
a. -2
Step-by-step explanation:
3¾ ≈ 4
-⅖≈ -½
4 × (-½) = -2
A reasonable estimate is -2.
hi <3
standard form is written in the form a x 10^n
where a is a number between 1 and 10
in this case, you would get 4.25 x 10^12
hope this helps :)
The tangent at A is perpendicular to OA, so has a slope that is the negative reciprocal of that of the radius: -1/2.5 = -2/5.
