Answer:
x = 4, -10
Step-by-step explanation:
Find the zeros of the equations.
Solve the equation:
x^2 + 6x = 40
Subtract -40 from both sides.
x^2 + 6x - 40 = 0
Factor the equation.
(x - 4)(x + 10)
Solve for x with the given information by equaling it to 0.
x - 4 = 0
Add 4 to both sides
x = 4
x + 10 = 0
Subtract 10 from both sides
x = -10
This means that our x values are:
x = 4, -10
I believe it would be 4x^18
Check: (4x^18)^2. You square the base so 16, and you multiply the powers so 36.
This "road" they are running is basically an L-shape, and combined with the direct distance from start to end forms a triangle. This triangle has a hypotenuse of 13 (since the direction of the road changes from south to west, we can pretty much assume that it is a right triangle with legs of 5 and X.)
So to find X, we use the Pythagorean Theorem.
a²+b²=c²
(5)²+X²=13²
25+X²=169
X²=144
Distance cannot be negative, so we know that X=12. This is the length of the remainder of the road.
To find total distance, just add the two lengths of road together.
5+12=17
Answer: x=-2/3
decimal form: x=-0.666...
Answer:
0
Step-by-step explanation:
since y=0 we can just plug that into the equation
2x+0=5x-0
3x=0
x=0
