Answer:

- 3y² - 7y + 6

Step-by-step explanation:

Given

(- 3y + 2)(y + 3)

Each term in the second factor is multiplied by each term in the first factor, that is

- 3y (y + 3) + 2(y + 3) ← distribute both parenthesis

= - 3y² - 9y + 2y + 6 ← collect like terms

= - 3y² - 7y + 6

klasskru [66]

Answer:

ans = 4

Step-by-step explanation:

he has 2 1\2 and 4 1\4

to find the ans, we must firstly find out his total amount of fabric, so we add the available fabric

first we add whole numbers

2 + 4 = 6

then we add fractions

1 1

--- + ---

2 4

2 + 1 3

------------- = ---

4 4

after we add the whole no and fraction

6 + 3\4 = 6 3\4

note 10 1\2 is greater than 6 3\4

so to find the part left, we

have

10 1\2 - 6 3\4

as our answer
