Answer:
x = 4
Step-by-step explanation:
the given figure is of an isoceles triangle.
The two angles opposite are congruent(i.e78 degrees) .
That is the sides opposite to them are also congruent.
I. e 4x + 23 = 10x - 1
I. e 4x - 10x = -1 -23
I. e -6x = -24
I. e -x. = -24/6
Dividing by 6 to 24 we get,
-x = -4
therefore by removing the minus sign from both the sides,
the answer comes x = 4
THE MULTIPLE OF 3 ARE: 3 , 6 , 9 ,12
The 1st magazine costs either 3 or 6 or 9 , 12
The 2nd magazine costs <span>3 or 6 or 9 , 12
The value 12 is to be discarded , then are the sum of tall possibilities to get 12:

Answer:
2.125
Step-by-step explanation:
If you work out the constants it says:
25+x²=100
Which simplifies to x=√75 or x=-√75
