Answer:
x = 50 in
Step-by-step explanation:
Since it is a right triangle we can use the Pythagorean theorem
a^2 + b^2 = c^2
14^2 + 48^2 = x^2
196 + 2304 = x^2
2500 = x^2
Take the square root of each side
sqrt(2500) = sqrt(x^2)
50 =x
x = 50 in
Answer:
3
Step-by-step explanation:
The equation being used to express the answer is called slope-intercept form.
y = m x + b
m is the slope, b is the y-intercept (where x = 0)
The formula to find slope (m) using two points is called point slope form.
m = (y1 - y2)/(x1 - x2)
Pick two coordinates and plug them in.
m = (1 - 4)/(0 - 1)
m = (-3/-1)
m = 3
The answer to this would be x = 20
Answer: third one
Step-by-step explanation:
Answer:
-a(a+4)/(16 - a²)
Step-by-step explanation:
a/(a - 4) Multiply by (a + 4)/(a + 4)
= a(a + 4)/[(a – 4)(a + 4)] Multiply the denominatorator terms
= a(a + 4)/(a² - 16) Multiply by -1/(-1)
= -a(a+4)/(-a² + 16) Reorder terms in denominator
= -a(a+4)/(16 - a²)
