1) (3m² + m - 5)+(3 - 6m² + 4m +5m)
a 4m5 – 3m² +6m - 2
b) 4m - 3m2 - 4m - 2
c) 4m - 3m2 -m-2
d) 4m +3m2 - 4m - 2

The answer to your question is: It could be letter A but power 5 is not necessary.

Step-by-step explanation:

Simplify like terms

1.- Remove parenthesis

                                      (3m² + m - 5) + (3 - 6m² + 4m + 5m)

                                       3m² + m - 5 + 3 - 6m² + 4m + 5m

2.- Group like terms

                                      (3m² - 6m²) + (m + 4m + 5m) + (3 - 5)

3.- Simplify

                                     - 3m² + 10m - 2

answer: the answer is 5/22

step-by-step explanation: if you subtract 17 from 22 the answer is 5 therefore the remainder of students are female

step-by-step explanation:   divide the numerator by the denominator to get the decimal

it would still be 193

if divide by 100 then 1.93
