Answer:
7x² - 3x - 4
Step-by-step explanation:
<u>Step 1: Write expression</u>
(6x² - x + 3) + (-2x + x² - 7)
<u>Step 2: Combine like terms (x²)</u>
7x² - x + 3 - 2x - 7
<u>Step 3: Combine like terms (x)</u>
7x² - 3x + 3 - 7
<u>Step 4: Combine like terms (constants)</u>
7x² - 3x - 4
Answer:
10, 14
Step-by-step explanation:
take the x values and plug into mid point formula and then divide by 2
so... (-214 + 234) divided by 2 = 10
do the same for the y values
so ... (14 + 14) divided by 2 = 14
so ... 10,14
The answer is 40 cause 4 times 9 = 36 so juat add the 0 to 4 and it makes it 40 times 9 ='360
