Answer: x=13
Explanation:
step 1 - multiply both sides by 6 to get rid of it
step 2 - simplify both sides
step 3 - subtract 1.4 from both sides
x = 13
Answer:
see below
Step-by-step explanation:
(2x + i)(2x – i)
FOIL
first 2x*2x =4x^2
outer -i * 2x = 2x i
inner i * 2x = 2x i
last i * -i = -i^2 and i^2 = -1 so - (i^2 ) = - (-1) = 1
Add together
4x^2 + 2xi -2x i +1
Combine like terms
4x^2 +1
Answer:
Rider A 450 Rider B 360
Step-by-step explanation:
Answer:
See below.
Step-by-step explanation:
Step 1.
Take the absolute value of the negative number.
Now both numbers are positive.
Step 2.
Subtract the smaller positive number from the larger positive number.
Step 2.
The sign of the answer is the same sign as the number with the larger absolute value.
Do 21/5 x 3/5 and you should get 63/25. Divide 63 by 25 and you should get 2 and 13/25.
