Answer:
Step-by-step explanation:
Firstly convert each number into an improper fraction. 2 1/4 would become: 9/4 (because we multiply 2 and 4 and plus the numerator, to get the numerator and keep the denominator the same). Do this to all the numbers then multiply the numerator by the numerator and the denominator by the denominator. simplify normally and convert to a mixed number.
Answer:
x=0 x=-5 x=2
Step-by-step explanation:
4x3 + 12x2 = 40x
Subtract 40x from each side
4x3 + 12x2 - 40x=0
Factor out 4x from each term
4x( x^2 +3x-10) =0
Factor the term insdie the parentheses
What 2 numbers multiply to -10 and add to 3
5*-2 =-10
5+-2 =3
We have (x+5) (x-2)
Replace that in the equation
4x ( x+5) (x-2) =0
Using the zero product property
4x= 0 x+5 =0 x-2 =0
x=0 x=-5 x=2
Answer: 85
Step-by-step explanation:
360degree for quad
thus
95+85+95 = 275
360-275 = 85
I assume you are studying implicit differentiation. Solving for dy/dx.
For the Left side use product rule. For Right side, use chain rule. Remember any time you take derivative of "y-term" you must multiply it by dy/dx.
--->

Get dy/dx terms on one side:

Factor out dy/dx and solve:
A square is made up of 4 equal sides all you would have to do to find the perimeter is divided 86 by 4 and that equals 21.5
21.5 should be your answer
