Answer:

(5x² + 3) - ( 2x² + 4x - 12) = 3x² - 4x + 15

Step-by-step explanation:

The given expression is

(5x² + 3) - ( 2x² + 4x - 12)

<u>To find the subtraction result</u>

(5x² + 3) - ( 2x² + 4x - 12) = 5x² + 3 - 2x² - 4x + 12

= 5x² - 2x² - 4x + 3 + 12

= 3x² - 4x + 15

Therefore the correct answer is

(5x² + 3) - ( 2x² + 4x - 12) = 3x² - 4x + 15

Answer:

Final answer is $3x^2-4x+15$

Step-by-step explanation:

Given expression is $(5x^2+3)-(2x^2+4x-12)$ .

Now we need to subtract them.

We are allowed to subtract like terms only that has same variable with same exponent.

$(5x^2+3)-(2x^2+4x-12)$

$=5x^2+3-2x^2-4x+12$

$=5x^2-2x^2-4x+3+12$

$=(5-2)x^2-4x+(3+12)$

$=(3)x^2-4x+(15)$

$=3x^2-4x+15$

Hence final answer is $3x^2-4x+15$

the taco truck sells tacos for $3 and burritos for $4. the number of items sold on a tuesday is 125 with a total income of $430.

butalik [34]

Answer:

Step-by-step explanation:

Hi, to answer this question we have to write a system of equations:

3 T + 4 B =425

T + B = 125

Where T is the number of tacos sold, and B is the number of burritos sold.

Multiplying the second equation by 3, and subtracting it to the first equation:

3 T + 4 B =425

3T + 3B = 375

___________

B =50

Replacing B in any equation:

T + B = 125

T +50 =125

T =125-50

T = 75

Feel free to ask for more if needed or if you did not understand something.
