Answer:
b. x + 2(x + 2) = x+2x +4 =3x+4
Step-by-step explanation:
simplify expression
(3x − 2x) + 2(2x − x) + 4 =
x + 2x + 4 =
3x+4
if x= 1 then 3x+4 =3*1+4 =3+4 = 7
if x= 3 then 3x+4 =3*3+4 =9+4 = 13
now that means when you plug in in given expressions 1 and 3 answers should be 7 and 13
or when you simplify expression it should be 3x+4 and that's b.
X^4 and 2x^2
all you have to do is substitute the coefficient if this is on e2020 the answer is d<span />
4/5*12/5
4*12=48, 5*5=25
so, 4/5*12/5=48/25
and 48/25=1 23/25
change to improper fractions
8 1/2 = (2*8+1)/2 = 17/2
2 1/4 = (4*2+1)/4 = 9/4
17/2 divided by 9/4
copy dot flip
17/2 *4/9
17/9 *4/2
34/9
change back to a mixed number
3 remainder 7
3 7/9
