Answer: 78

Step-by-step explanation:

Step 1:

Substitute the variables in:

6(9) - 8(-3)

Step 2:

Multiply to get rid of the parentheses:

54 - -24 = 54 + 24 (the two negatives cancel out)

Step 3:

Add, and then you're done:

54 + 24 = 78

hope this helps :)

(9x2 + 10x + 4) − (9x2 + 5x − 1)

ch4aika [34]

For this case we must simplify the following expression:

$(9x ^ 2 + 10x + 4) - (9x ^ 2 + 5x-1)$

We eliminate the parentheses taking into account that:

$- * + = -\\- * - = +\\9x ^ 2 + 10x + 4-9x ^ 2-5x + 1 =$

We add similar terms taking into account that:

Equal signs are added and the same sign is placed.

Different signs are subtracted and the major sign is placed.

$9x ^ 2-9x ^ 2 + 10x-5x + 4 + 1 =\\5x + 5$

Answer:

$5x + 5$
