Ted has to read a book that is 1000 pages long
he read 100 pages on Tuesday
On Wednesday, He read twice the number of pages that he read on Tuesday
on Thursday he read 396 pages
how many more pages does he have to read?
so the solution would be 1000- (100+2(100)+396)=x find x
Answer:
x=-1, x=2, x=3
Step-by-step explanation:
Factor the left side of the equation.
(x+1)(x^2+x-6)
(x+1)(x-2)(x-3)
Now set everything equal to 0
x+1=0
x-2=0
x-3=0
Now solve for x
therefore, the answer is x=-1, x=2, x=3
8+20-2r which is equal to 28-2r so it is (B)
Solution for 1/5(5x+12)=18 equation:
<span>x in (-oo:+oo)
(1/5)*(5*x+12) = 18 // - 18
(1/5)*(5*x+12)-18 = 0
1/5*(5*x+12)-18 = 0
1/5*(5*x+12)-18 = 0
x-78/5 = 0
x-78/5 = 0
x-78/5 = 0 // + 78/5
x = 78/5
x = 78/5

(3t² +t -12t - 4)(t+2)=0
(3t³ - 5t² -26t -8) =0
t = -2
