Answer:
numbers are 3x,2x,5x
so 3x+2x+5x=10x=840
so x=84
so numbers are 252,168,420
Answer:
hi :D
Step-by-step explanation:
use PEMDAS (parenthesis first)
4 * (x * 3) =
4 * 3x =
12x
Multiply and simplify (3 + i)(4 + 2i)
(3 + i)(4 + 2i) = (3*4) + (3*2i) + (4*i) + (2i*i) = 12 + 6i + 4i + 2i^2
i^2 = -1
12 + 6i + 4i + 2i^2 = 12 + 6i + 4i -2 = 10 + 10i
Use the imaginary number i to rewrite the expression:
-
Part A: $225y+5x=$480
Part B: f(480)=225=5x
Part C: I'm not sure how to do this but I hope that A and B helps!
