x=375-296
x=79
Answer:
9x-2
Step-by-step explanation:
Since you are adding the two functions, you should first start adding like terms. 4x + 5x is 9x. -8 + 6 is -2. Thus the value of (f+g)(x) is 9x-2.
5/10 *2/4
Cross out 2 and 10, divide by 2. 2/2=1 , 10/2=5
5/5*1/4= 5/20
reduce the fraction
divide by 5 for the numerator and denominator
5/5=1
20/5=4
5/10*2/4=1/4
Answer: 1/4
