Answer:
5.39
Step-by-step explanation:
if you are trying to find MN then it means you need to find the length.
we cant use slope, but we CAN make it a triangle!
*see the attached image*
we can use A^2+B^2 to get what the hypotenuse is or C^2 is
2^2+5^2
4+25=29
the square root of 29 is 5.385
then we just round to the hundreth!
5.39
(8>5, so we bump him up)
hope this helped!
(3x^2+9x-6) - (2x^3-4x^2+6x-4)
Short Answer
2x^3+7x^2+3x-2
Step by Step
1.)2x^3 doesn’t subtract from anything because there are no other trinomials
2.)3x^2 - (-)4x^2 = 7x^2 because a double negative cancels out and you end up adding them
3.)9x-6x=3x
4.)-6 - (-)4 = -2 because double negatives cancel out into addition
A) Yes. There is 3x as much dry dog food as there is wet dog food. 1.5 x 3 = 4.5 oz. 2 x 3= 6 oz. 3 x 3 = 9 oz
b) 16.5. (5.5 x 3 = 16.5)
