\huge\textsf{Hey there!}

\mathsf{2x^2 + 3x - 12}

\mathsf{= 2(5)^2 + 3(5) - 12}

\mathsf{5^2}

\mathsf{= 5 \times 5}

\mathsf{\bf = 25}

\mathsf{2(25) + 3(5) - 12}

\mathsf{2(25)}

\mathsf{= \bf 50}

\mathsf{3(5)}

\mathsf{= \bf 15}

\mathsf{= 50 + 15 -  12}

\mathsf{50 + 15}

\mathsf{= \bf 65}

65 - 12

\mathsf{= \bf 53}

\boxed{\boxed{\huge\textsf{Answer: \bf 53}}}\huge\checkmark

\large\textsf{Good luck on your assignment and enjoy your day!}

10. Victoria has a coupon for 30% off of any item in a department store. She decides to purchase a treadmill. The original price
KonstantinChe [14]

Answer:

Step-by-step explanation:

Original price $595.00

Discount amount 595(0.30) = $178.50

Pre tax price 595.00 - 178.50 = $416.50

tax amount 416.50(0.07) = 29.155 = $29.16

cost to Victoria 416.50 + 29.16 = $445.66

Marcel made an error when he used the distributive property to write an equivalent
natima [27]

Answer: Upper left corner

Explanation:

The error happens in step 2. Notice that x is <u>not</u> part of the second term 16, so there's no way to factor x from it unless you want a fraction to result.

The second step should be 8(4x-2)

Another way to factor is to say 16(2x-1)
