the answer is 1/10 :))))))))
Answer:
ab² - 9
Step-by-step explanation:
Given in the question an expression
(ab + 3)(ab - 3)
To product mentally we will use polynomial identity called
Difference of squares
<h3>a² - b² = (a+b)(a-b) </h3>
here a = ab
b = 3
(ab + 3)(ab - 3) = ab² - 3² = ab² - 9
Answer: x=17 (if that’s what you mean)
explanation: a straight line is 180 degrees, so we can minus 180-115 which will give you 65, and if you set the equation given equal to 65, you’ll get 17
It would be 600 miles in 24 hours if it continues to fly at the same speed cause every 2 hours the distance goes up by 50.
Assuming you need to solve for x:
-6(x + 6) - 10 = -2(5 + 4x)
start by distributing your numbers outside the front of your parentheses:
-6x - 36 - 10 = -10 - 8x
then combine like terms:
-6x - 46 = -10 - 8x ... add 10 to both sides (which technically could have cancelled out in the step prior, but regardless)
-6x - 36 = -8x ... add 6x to both sides
-36 = -2x ... divide both sides by -2
x = 18
