The least common denominator is 150. 15x10 = 150, and 50x3 = 150
Answer:
Step-by-step explanation:
The ladder forms a right angle triangle with the wall. The straight line distance from the bottom of the window to the ground forms the opposite side. The distance from the bottom of the ladder to the house represents the adjacent side. To determine the required length of the wire, c, we would Pythagorean theorem which us expressed as
Hypotenuse² = opposite side² + adjacent side²
Therefore,
c² = 6² + 5² = 36 + 25 = 61
c = √61 = 7.81 ft
You just substitute the value of x in the given equation:
f(x) = 2x^2 - 5
f(-4) = 2 (-4)^2 -5 = 27
f(x) : a name given to the equation
f(-4): refer to the equation when the value of the independent variable x has the value between the brackets.
There are many like
1(10)+10-1=19
18+1=19
30-11=19
15+4=19
Hope this help!!
The answer is division and subtraction. I hope you get it right
