If you would like to write <span>(-3 + √-9)^2 in a standard form a + i * b, you can do this using the following steps:

</span>(-3 + √-9)^2 = (-3)^2 - 2 * 3 * √-9 + (<span>√-9)^2 = 9 - 6 * 3 * i - 9 = 0 - 18 * i = -18 * i
</span>
The correct result would be -18 * i.

Pleseeeeeeeeeeeeeee helllllllppppp fassttttty pleaseeeeeeeee​
DENIUS [597]

Answer:

0.10

Step-by-step explanation:

0.15 =  \frac{15}{100}  \\ 0.40 =  \frac{40}{100}  \\ 0.35 =  \frac{35}{100}  \\

Since all of them have the denominator as 100,

the total no. of sweets must be 100. So,

No of strawberries= 100-15-40-35

= 10

p(taking a strawberry sweet)= 10/100

= 0.10

What is the sum of –356.1 + 258.6
xxTIMURxx [149]

Answer:

Step-by-step explanation:

-356.1 + 258.6 = -97.5

Imagine a long timeline with 0 in the middle, on the left we have -356.1 and on the right we have 356.1. Adding numbers makes the timeline move right.

Starting from the left, add (+) 258.6 to the number (moving right along the timeline). As 356 is larger than 258, the scale does not reach 0 yet and therefore the number must be negative.

Using this logic, the answer is 97.5
