Answer:
62 and 63
Step-by-step explanation:
n + n + 1 = 125
2n + 1 = 125
2n = 124
n=62
Answer:
12^2x = 7^4 = 2401
7^2=12^x
We know that a^x * a^x = a^(x+x) or a^2x
Multiply each side by 12^x
7^2 * 12^x=12^x * 12^x
7^2 * 12^x = 12^(x+x)
Replace 12^x with 7^2 on the left hand side since they are equal
7^2 * 7^2 = 12^ (2x)
7^(2+2) = 12^(2x)
7^4 = 12^2x
2401 = 12^2x

Answer:
E. - 7
Step-by-step explanation:
2x2-X2+5X-10-4=0
X2+5X-14=0
X2-2X+7X-14.=0
X(X-2). 7(X-2)=0
(X+7). (X-2)
X=-7, X=2
Number 3 is correct
the next one is 1.62614012X10^-7
I'll do it step by step:
3(x+2(3))=7(3)-9
3(x+6)=21-9
3x+18=12
I don't know what x is, so I think that's as much as I can do.
