Answer:
x=-5/2, -3
Step-by-step explanation:
2x^2+11x+15=0
factor out the trinomial
(2x+5)(x+3)=0
zero property,
2x+5=0, x+3=0
2x=0-5=-5, x=-5/2
x=0-3=-3
Answer:
n=12
Step-by-step explanation:
3.3(n-8)-n=1.2
Distribute
3.3n -26.4 -n = 1.2
Combine like terms
2.3n -26.4 = 1.2
Add 26.4 to each side
2.3n -26.4+26.4 = 1.2 +26.4
2.3n = 27.6
Divide each side by 2.3
2.3n/2.3 = 27.6/2.3
n=12
You have to multiply 3 times 2= 6 + 4 = 10 so the answer is 10 I hope this help...
Answer:
LCM(9, -1, -1, +2, +2, +2) = 2×3^2 = 18
Step-by-step explanation:
9 = 32
-1 = -1
-1 = -1
+2 = 2
+2 = 2
+2 = 2
LCM = 2×3^2 = 18
18 / 9 = 2
18 / -1 = -18
18 / -1 = -18
18 / +2 = 9
18 / +2 = 9
18 / +2 = 9
I think it would be true because they are crossing
