Answer:
=6
Step-by-step explanation:
(5×8)×(5-2)/(5×4)
Numerator =40×3
=120
Denominator = 5×4
=20
simplifying 120/20
=6
Let's call the width: w
the lenght is then 3w+4 ("4 more than 3 times the width")
and the parameter would be 2(w+3w+4), that is 2*(4w+4), that is 8w+8.
this is also equal to 18.4:
8w+8=18.4
8w=10.4
w=1.3
this is the width, and the lenght is:
4+3*1,3=4+3.9=7.9
and the area is their product:
1.3*7.9=10.27
Answer:
-3x + 5.
Step-by-step explanation:
(f + g)(x) = x + 8 - 4x - 3
= -3x + 5.
21.5, just took the test!!!!
Since both 3x and 6x have the variable x in it, we can just go ahead and add 3 and 6.
3x+6x=9x
