Answer:
The formation of the equation is odd, but I assume it's supposed to be:
4k - 10k = -8k
-6k = -8k
-6k + 8k = -8k + 8k
2k = 0
= 
k = 0
Answer:
-84+48i
Step-by-step explanation:
Answer:
x = 14
Step-by-step explanation:
I don't know which one you are supposed to solve it by so I will do both.
Solution by Cross Multiplication
For the equation
7x=24
The cross product is
7×4=x×2
Solving for x
x=7×42
and reducing
x=14
Solution by Proportion
Since the equation is an equality
If
7 ÷ 2 = 3.5
Then it is true that
x ÷ 4 = 3.5
Solving for x
x = 4 × 3.5
x = 14
Answer:
3=140°
Step-by-step explanation:
Answer:
3x^2+11x-20
Step-by-step explanation:
step 1 3x(x+5)-4(x+5)
step 2 3x(x+5)-4(x+5)= 3x^2+15-4(x+5)
step 3 3x^2+15x-4x+20
