Step-by-step explanation:
8-12x=-6(34x-2)+4
8-12x=204x-12+4
subtract 8 from both sides.
-12x=204x-20+4
-12 turned to -20 because we subtracted 8.
add 20+4
-12x=204x-24
subtract 204x from both sides
-216x=-24
divide by -216x
So I would say it has infinitely many solutions
Let me help ya
Step-by-step explanation:
lol I do iready too so first replace the varbile with what ever number they have then you multiply it
K² + 13k + 30 = 0
This is a quadratic equation. Let's attempt solving it by factorization.
Coefficient of k² = 1, last term = 30
Multiply these two together 1*30 = 30
We think of two numbers that multiply to give 30 and add to give the middle term 13.
The two numbers are 3 and 10.
3*10 = 30, 3 + 10 = 13.
we replace the 13k with 3k + 10k
k² + 13k + 30 = 0
k² + 3k + 10k + 30 = 0
k(k + 3) + 10(k + 3) = 0
(k + 3)(k + 10) = 0
(k + 3) = 0 or (k + 10) = 0
k = 0 - 3 or k = 0 - 10
k = -3, or -10
I hope this helps.
Answer:
A
Step-by-step explanation:
Acids turn litmus paper red. The characters of acids are given by substance A. An acid tastes sour and also conducts electricity well because of ionization properties. Additionally, Hydrogen gas is produced from acid-base neutralizations because most if not all acids contain hydrogen.
