Answer:
-1311
Step-by-step explanation:
1316 + x = 5
Subtract 1316 from both sides:
1316 - 1316 + x = 5 - 1316
On the left side they cancel out and we are left with:
x = 5 - 1316
Which simplifies to:
x = -1311
Answer: x= 2(2+sqrt(10)) , x=2(2-sqrt(10)
Step-by-step explanation:
x^2-8x=24 <- subtract 24 from both sides
x^2-8x-24 <- take quadratic formulat (-2+/- Sqrt(b^2 - 4ac)/2a
-(-8) +/- sqrt((-8)^2 - 4(1*-24) all over (2*1) <- simplify
(-(-8) +/- 4sqrt(10) )/2 <- sepereate
(-(-8) +/4sqrt(10) )/2 , (-(-8) - 4sqrt(10) )/2 <- simplify
2(2+sqrt(10)) , 2(2-sqrt(10) =x
You will have to get the -3x by itself so you will add 6 to both sides so -3x-6+6-5+6 and you will get -3x=11do you need anymore help?
You can use my photo as reference but its going to be 15/100 of 480
