Answer:

\boxed{ \bold{ \boxed{ \sf{12 {x}^{2}  - 13x - 14}}}}

Step-by-step explanation:

\sf{(3x + 2)(4x - 7)}

Use the distributive property to multiply each term of the first binomial by each term of the second binomial

\longrightarrow{ \sf{3x(4x - 7) + 2(4x - 7)}}

\dashrightarrow{ \sf{12 {x}^{2}  - 21x + 8x - 14}}

Collect like terms

\longrightarrow{ \sf{12 {x}^{2}  - 13x - 14}}

Hope I helped!

Best regards! :D

Answer:

12x^{2}  + 29x - 14

Step-by-step explanation:

(3x+2)(4x-7)

Multiply out 3x first then 2

(3x * 4x) - (3x * -7) + (2 * 4x) + (2 * -7)

12x^{2} - (- 21x) + 8x + ( -14)

12x^{2} + 21x + 8x - 14    Combine like terms

12x^{2}  + 29x - 14

HELP!!! CORRECT ANSWER NEEDED OR ELSE I FAIL ;-; STUDY ISLAND !!
Ket [755]

Answer:

  B.  Step 2 uses the associative property, and step 3 uses the commutative property.

Step-by-step explanation:

The associative property lets you group terms for addition any way you like. It appears that in Step 2, the grouping is ...

  4 + (1/6 + 3) + 5/6

The commutative property lets you change the order of any pair of terms involved in addition. It appears that in Step 3, the order of the terms within the group has been swapped.

  4 + (3 + 1/6) + 5/6

_____

<em>Comment on associative and commutative properties</em>

What applies to terms in addition applies to factors in multiplication.

Peter buys a camper van costing £35000 + 20% VAT. He pays a 50% deposit and then arranges to pay the remaining balance in 20 equ
shutvik [7]

The amount paid each month is 1050.

35,000 plus 20% is 42,000 because 20% of 35,000 is 7,000.

Next, divide 42,000 by 20, and you would get 1050.
