I'm gonna do number 8 but do the SAME steps for the rest.....take the denominator multiply it by the whole number then add that answer to the numerator so now it will be 23/5×15/4 ... once u have that just multiply across but DON'T CROSS MULTIPLY multiply straight across and u'll get ur answer... answer to 8 is 345/20 now divide that answer like this.. 345÷20= 17.25
(1+i)/(1-i)
(1+i)/(1-i) • (1+i)/(1+i)
(1+i)(1+i)/(1-i)(1+i)
(1+2i+i^2)/(1+i-i-i^2)
(1 + 2i - 1)/(1 - i^2)
(2i)/(1 - (-1))
(2i)/(1 + 1)
2i/2
i
Answer:
14 squared
Step-by-step explanation:
Let's look at the formula to solve the perimeter.
2l+2w=98
We know that l=6w
Let's put that into the equation.
2(6w)+2w=98
12w+2w=98
14w=98
98÷14=7
So the width is 7. Let's find the length.
Since the length is six times the width: 7×6= 42
So, the length is 42 while the width is 7. We need to find the area.
42×7=294
The area is 294 m².

Answer:
-77, -78, -79
Step-by-step explanation:
let one of the integers be x
since the integers are consecutive, the other 2 integers must be
(x+1) and (x+2)
given that sum of the integers is -234,
x + (x+1) + (x+2) = -234
x + x + 1 + x + 2 = -234
3x + 3 = -234 (subtract 3 from both sides)
3x = -234-3
3x = -237 (divide both sides by 3)
x = -237 / 3
x = -79 (answer)
hence the other two numbers are
(x + 1) = -79 + 1 = -78 (answer)
and
(x+2) = -79 + 2 = -77 (answer)
