Answer:
x = 8
Step-by-step explanation:
3(x−5) = 9 (by PEDMAS, distribute 3 into parentheses by distributive property)
x(3)−5(3) = 9
3x - 15 = 9 (add 15 to both sides)
3x = 9 + 15
3x = 24 (divide both sides by 3)
x = 24/3
x = 8
The answer is 30.
Sorry Last time I found the LCM of the answers.
Answer:
6/8, 9/12, and 15/20
Step-by-step explanation:
just do 3 divided by 4 (3/4) and it equals 0.75 then do each and everyone like 6 divided by 8 (6/8) so it equals 0.75
F(1)=0 so x=1 is a zero => x-1 is a factor 1 | 1 -8 -23 30 | 1 -7 -30 --------------------- 1 -7 -30 | 0 x^2-7x-30 is another factor x^2-7x-30=(x-12)(x+5) x=12, x=-5 our roots too s0 1+12+(-5)=13-5=8
