Answer:
see below
Step-by-step explanation:
12.5x − 10.2 = 3(2.5x + 4.2) - 6
Use the distributive property to distribute the 3
12.5x − 10.2 = 7.5x + 12.6 − 6
Combine like terms
12.5x − 10.2 = 7.5x + 6.6
Add 10.2 to each side of the equation by using the addition property of equality
12.5x = 7.5x + 16.8
Subtraction 7.5x from each side of the equation by using the subtraction property of equality
5x = 16.8
Divide by 5 on each side by using the division property of equality
x = 3.36
D= (12)/(3)(4)
d = 12/12
d = 1
The answer should be 7 on the outside and 3 on the inside
Answer:
= 16+49 = 65
Step-by-step explanation:
The error is at the end of the first line. (-7i)(7i) = -49i² ≠ +49i².
The correct work is ...
(4-7i)(4+7i)=16+28i-28i-49i^2
= 16+49
= 65
Answer:
