I am pretty sure that addiction because if you add 198 6 times it woyuld be the same as multiplyaction
Answer:
3x+2y=15--------(1)
4x+2y=20--------(2)
then, 2y=15-3x------(3)
putting value of 2y in equation (2)
4x+15-3x=20
x=5
then after , putting value of x in eq(3)
y=(15-15)/2
y=0
Answer:
Option D
Step-by-step explanation:
The pythagorean equation states that a^2+b^2=c^2, with c^2 being the hypotenuse and a^2 and b^2 being the legs. if you input the values into the formula you get 2^2 + 6^2 = 40. 40 does not square evenly so you have to convert √40 into simplest radical form. when you do this you get 2√10

Answer: The ladder is sliding down the wall at a rate of 
Step-by-step explanation:
Since we have given that
Length of ladder = 25 foot
Distance from the wall to the bottom of ladder = 15 feet
Let base be 'x'.
Let length of wall be 'y'.
So, by pythagorus theorem, we get that


Now, the equation would be

Differentiating w.r.t x, we get that

Hence, the ladder is sliding down the wall at a rate of 
Answer:
