Evaluate \( \frac{156}{8x+14} \) when \( x = 8 \).

Asked by icarley01

Answer (3)

so first we have to find out what the bottom number is so
8x+14 subsitute 8 for x 8(8)+14 64+14 78
so 156/78 an easy way to do this is to factor it out and find the 'ones' like 4/8=1/2 times 4/4 (4/4=1 and can be canceled out) =times 156=2 2 3 13 78=2 3 13
so (2 2 3 13)/(2 3 13) 2/1 times (2 3 13)/(2 3 13) we can cross out the (2 3*13) and get 2 as the answer
