Answer:
x= -1 or x = -2
Step-by-step explanation:
Your equation:
(x−3)^3−(x−1)^3+7x^2=7(3x−4)
Step 1: Simplify both sides of the equation.
x^2+24x−26=21x−28
Step 2: Subtract 21x-28 from both sides.
x^2+24x−26−(21x−28)=21x−28−(21x−28)
x^2+3x+2=0
Step 3: Factor left side of equation.
(x+1)(x+2)=0
Step 4: Set factors equal to zero.
x+1=0 or x+2=0
which equals to x=−1 or x=−2
Answer:
It is an improper fraction.
Step-by-step explanation:
With fractions, if the numerator is equal to or grater than the denominator, the fraction is considered an improper fraction.
Step-by-step explanation:
2(v-4)-5v
= 2v-8-5v
= -3v-8
One seventh of 14 = 9.8 and half of 36 is 18 so half of 36 is larger
