Answer:
The situation best for the equation 3x=288 Is by dividing both sides by the coefficient of x to single out the variable
Step-by-step explanation:
=> 3x/3=288/3
=> x = 96
Ax^2 + bx + c
a = 1
b = -4
c = -5
x^2 -4x-5
-5x1 = -5
-5+1 = -4
(factors of c that also add up to b)
ANSWER: (x-5) (x+1)
<span>If you divide 63 by 3 you get 21 which means that on Sunday she skied for 21 miles and On Saturday for 42 because she skied twice as many miles on Saturday.

Answer:
x = √5 + 4 , -√5 + 4
Step-by-step explanation:
3(x - 4)^2 = 15
/3 /3 (divide both sides by 3)
----------------------
(x - 4)^2 = 5
(x−4)^2⋅1/2 = ±√5 (take square root of both sides)
x - 4 = ±√5 (add 4 on both sides)
+ +4
-----------------
x = √5 + 4 , x = -√5 + 4
