AB’s radius can be found by dividing 8 in half to get 4. While CD’s radius can be found by dividing 6 in half to get 3
Answer:
3(x^y(5x^2y-x³)+25x⁴))
Step-by-step explanation:
15x^2y²-3x^3y+75x⁴
From 15x^2y²-3x^3y only, 3x^y is the common factor
=> 3x^y(5x^2y-x³)+75x⁴
Taking the common factor of the latter expression, 3 shows to be the common factor of all the expression.
=> 3(x^y(5x^2y-x³)+25x⁴)
Answer:
Step-by-step explanation:
Twice the sum of a number of 11 is -38
2( number +11) = -38
number +11 = -38/2
number = -19 -11
number = - 30
