Answer:
Step-by-step explanation:
-2x2-12x-15
Final result :
-2x2 - 12x - 15
Step by step solution :
Step 1 :
Equation at the end of step 1 :
((0 - 2x2) - 12x) - 15
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
-2x2 - 12x - 15 = -1 • (2x2 + 12x + 15)
Trying to factor by splitting the middle term
3.2 Factoring 2x2 + 12x + 15
Answer:
about 37.57
Step-by-step explanation:
basically multiply the original number by 6 then add 17 then divide it by seven. I think. dont hate me if im wrong. im kinda dumb
Answer:$259
Step-by-step explanation:
since we need to increase $250 by 6%, it is useful to find one percent because 1% is easy to find
to find one percent of 250, we move the decimal point(we cant see it right now) from after the number to after 2 giving us 2.50. we need to do this to find one percent because 1% is the same as one HUNDREDth, and since 100 has two zeros, we move the decimal place two spaces.now that we know that 1% is $2.50 ( which is the same as $2.5) we can times that by six which gives us 6%(because one times 6 is 6) to multiply 2.5 by 6, we first multiply 6 by 2 which will give us 12 and then multiply it by 0.5 (because 2 + 0.5 =2.5) 0.5 multiplied by 6 is equal to 3 and 3 + 6 = 9. we know know that 6% of $250 is $9. we now just add 9 to 250 leaving us with $259

Answer:
(x - 10)(x + 10)
Step-by-step explanation:
x² - 100 ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , then
x² - 100
= x² - 10²
= (x - 10)(x + 10)
