Answer:

2y2+9y−10

Step-by-step explanation:

Distribute the Negative Sign:

=−2y2+6y−1+−1(−4y2−3y+9)

=−2y2+6y+−1+−1(−4y2)+−1(−3y)+(−1)(9)

=−2y2+6y+−1+4y2+3y+−9

Combine Like Terms:

=−2y2+6y+−1+4y2+3y+−9

=(−2y2+4y2)+(6y+3y)+(−1+−9)

=2y2+9y+−10

which strategy do you prefer to use to multiply with multiples of 10: base ten blocks, a number line, or place value? Explain wh

Place value. when multiplying by 10 you are moving a decimal, having everything lined up like place value would save you a lot of time.

Simplify.<br> (w^2 + 3w)-(w^2+5w-4<br><br> 8w-4<br> 2w^2 +8w-4<br> -2w+4<br> -2w
chubhunter [2.5K]

Answer:

-2w + 4

Step-by-step explanation:

Remove parenthesis because they make life semi-confusing but remember to distribute the negative: w^2 + 3w -w^2 - 5w + 4

Combine like terms: w^2 - w^2 cancel out ; 3w - 5w = -2w ; 4

-2w + 4
