Multiply (x+3)(3x+8) x times 3x =3x^2 then multiply x times 8 = 8x
keep multiplying 3 times 3x =9x then 3 times 8=24
then multiply the -3x(x+3)= -3x^2-9x
your hole expression will look like this 3x^2+8x+9x+ 24-3x^2-9x
if you need to simplify you can do by adding or subtracting them.
for example you can add 8x+9x= 17x
Answer:
a=-4
b=-4
Step-by-step explanation:
-0.113 blank =0.452x + 0.452
-0.113(a+bx) =0.452x + 0.452
-0.113a-0.113bx =0.452x + 0.452
so we have
-0.113a=0.452
a=-0.4520/0.113= -4
-0.113bx =0.452x
b=-0.452/0.113= -4
Answer:
x ≤ - 
Step-by-step explanation:
Given
3x + 14 ≤ 13 ( subtract 14 from both sides )
3x ≤ - 1 ( divide both sides by 3 )
x ≤ -
