Answer is 6-4x
<span>1/4 evaluates to 1/4
</span>
<span>Multiply x and 16
</span>
<span>Multiply x and 1
after you have the answer it should come out to </span>24-16x then multiply 1/4 * 24-16x
1/4 *24=6
<span>1/4*(24-16*x) evaluates to 6-4x</span>
B. x > -4 I did da test. That's da correct one :-)
The three numbers are 12, 18 and 24
Arithmetic progression
Let the 3 number in arithmetic progression be:
a-d, d, a+d ...
If their sum is 3, then;
a-d+d+a+d = 3
2a + d = 3 ........... 1
If the sum of their squares is 11, then;
(a-d)² + d² + (a+d)² = 11
a²-2ad+d²+d²+a²+2ad+d² 11
2a²+3d² = 11 ....... 2
Solving the equations simultaneously, d = 6 and a = 12
First-term = 12
second term = 18
Thirs term = 24
Hence the three numbers are 12, 18 and 24
Hope this helps you!!!!!! :D
